If you look at a problem from one angle, you will look at the problem from different angles

**Not easy to draw.

Look at it yourself and draw it at the same time.

The point where the observer is located is A, and the center of the balloon is O

The tangent of the two lines of sight and the balloon tangent to the two points b and e.

Let the distance from the observer to the center of the balloon be p

Then the height h of the balloon from the ground is p*sin60°

The view of the balloon.

i.e. bae) is 2°

So angular bao=1°

So in the right triangle abo, ao=p

ao*sinbao=p*sinbao=r

p=r/sinbao

sinbao angle bao = (1 180) * pi (must be turned into radians to be true).

In this way, find p, and bring in h=p*sin60°

Just find H.

The point where the observer is located is A, and the center of the balloon is O

The tangent of the two lines of sight and the balloon tangent to the two points b and e.

Let the distance from the observer to the center of the balloon be p

Then the height h of the balloon from the ground is p*sin60°

The view of the balloon.

i.e. bae) is 2°

So angular bao=1°

So in the right triangle abo, ao=p

ao*sinbao=p*sinbao=r

p=r/sinbao

sinbao angle bao = (1 180) * pi (must be turned into radians to be true).

In this way, find p, and bring in h=p*sin60°

Solid geometry problems. The straight line between the observer and the center of the sphere is perpendicular to the diameter of the sphere, and the two ends of the diameter are b and e, then c is the midpoint of be, and ac is perpendicular to be.

In the isosceles triangle BAE, the observation point angle A = 2° = Pi 90, then the angle BAC=1 2*A = Pi 180, and BC=4 2=2M, so AC=BC Tan (angle BAC). Because when (in radians) is very small, tan so ac=bc angle bac=2*180 pi.

The elevation angle of the balloon center c at surface A is 60°, so the height of the balloon center c from the ground is ac*sin60°=2*180 pi*sqrt(3) 2=m.

First draw a circle for the balloon, the center of the circle is c, draw a straight line directly below the circle for the ground, take a point on the line A for someone's location, cross the vertical line of C to make a straight line at D, do a tangent line with the balloon circle at point A, the tangent point above is B, the bottom tangent point is E, then bae=2°, and CB is perpendicular to AB, CE is perpendicular to AE, cae=1°, in the triangle ace there is sin cae=ec ac, ec=2m, then ac=2 (1 180)=360 m, The projection of point C on the ground is d, cd is vertical AD, cad=60°, and the height of c from the ground.

cd = ac*sin60 = 180 times the root number 3 m = m

That angle of view (i.e. BAE) is 2°, which is the visual angle of seeing both sides of the balloon, which is the angle between the tangents of the two balloons from point A, and C is the center of the ball, so there is a right triangle ABC angle CBA is a right angle.

Connected AC, angle BAC=1° BC AC=sin1° 1°=180, BC is a radius of 2m

So ac=360

The angle between the vertical height of point c and the line of sight is 30°, so it is easy to find the vertical height, (180) * root number 3=

There is no way to make a drawing, you can draw it with straw paper, a 30° angle of the right angle trigram, 30° acute angle on a circle with a radius of 2, in the other corner of the tangent line of the two circles, the angle between the tangents is 2°!! over

We feel that no one loves me, no one cares about me, I can't be what I am, I should be what others expect, it's all because I'm not good enough.

And the Buddha said: You are the Buddha, and the Buddha is in your heart.

Miracle says: You were born to be perfect, but there are some obstacles that keep you out of sight.

Satya said: You have all the resources within you, and you are the unique manifestation of life.

Born with a tendency to self-actualize. Just as an acorn seed grows into an oak tree, if obstacles are removed, a person will naturally develop into a mature, fully realized individual.

For those of us who are not happy with our lives, we should think more about these questions:

I think this paragraph is quite redundant, but I want to put this young lady here. ）

We look at the problem from the point of view: I am missing, I am bad, I am not enough, I want to be whole, to be good, to be enough.

Before, we would only look at the problem from one direction: he was short-tempered and inhumane; He is timid and fearful, weak and incompetent; There are all the bad things about him, and I'm a bad guy when I meet him. This is enough to lose the balance of experience.

Now let's add another angle: his behavior, probably because he feels threatened, he has to fight for himself or hide to survive; And because no one had taught him any other way to express his needs and desires for intimacy. Add things like opening things, unclogging pipes, removing obstacles, so that we have more possibilities to move towards stability and balance.

Not only can we see things from multiple angles in one plane, but we can also improve our dimensions to see things and understand what is happening.

The Awakened One mentions that the best way to solve a problem is to raise your dimension and add the fourth dimension to our consciousness, so that many of the problems that plague you in the three-dimensional world are no longer a problem.

From a rational or informational point of view, it can be understood. But there's no way to understand how it happened. With an open mind, let's take our time to observe, learn, and experience.

Lately, I've been thinking about what is learning and what is it for? The children in my hometown are still learning the same way we used at the time, and the poor teachers didn't add new methods, and even encouraged the children to cheat just to get a good grade.

suddenly thought, "It is difficult to produce a noble son from a poor family". Guizi is learning to experience the world in a wider dimension, while our children are getting further and further away from the experiential function of existence. The result of my thinking:

Learning, firstly, is to have a skill to survive, and secondly, the scum is to be able to look at problems from multiple angles and solve problems from a higher dimension.

Life is only a hundred years, and there is no meaning in the illusion of day after day. Standing high, seeing widely, people can travel this time, and they can have more fun.

The same number, the position of the station is different, so the view is different. Everyone thinks differently, so people believe what they see. That's why there is a disagreement, standing in your position, you see 5 and standing opposite you sees 2.

Don't underestimate this 5, if it's a ten-point system, then this 5 is half. Often, most things are half probable, and the final result will be different if the choice is different. Let's talk about the 2 you see from the opposite angle, because you know that one thing has half the success rate, because you see that half of the success rate.

But from the other party's point of view, what you see is 2, because you can't see through the thing itself, and you are not the same thinking, so you will see 20%, so when you go to implement and do something, most people often don't understand you, and people who don't understand the facts themselves often say that you are two.

However, even if the other person is on the same page as you, the way he sees things will hinder you. What you see is 5 percent certainty, and what the other party sees is 5 percent unknown. So it will be blocked.

Therefore, you don't need to completely listen to other people's opinions on everything, and don't leave things that you should be thinking about to others to do. This is equivalent to giving your brain to someone else, letting someone else think for you, and in the long run, you will lose your own value. And losing value is equivalent to losing some competitiveness.

Life is a process of self-change. Unchanged is called life, or growth, and transcending oneself is called growth.

These are all problems of judging parallel lines, and it is examined whether the conditions for parallel lines are mastered: if the angle of the same or the angle of internal error is equal, then the two straight lines are parallel; Extend past: two lines perpendicular to or parallel to the same line;

1. ap bq, and ap=bq; AP EF (or AB), BQ EF (or AB), AP and BQ are all parallel to the same straight line EF;

2. cnf= bme, the vertex angle dnm= cnf, bme= dnm, the two angles are the isotope angles of the straight line ab and cd truncated by the straight line ef, ab cd;

emp= bme+ 1= dnm+ 2= mnq, the isotope angles of the straight line mp and nq are equal by the straight line ef, ab cd;

3、ab∥cd；abc=2 1=2 2= dcb, the inner error angle of the straight line ab and cd intercepted by the straight line cb is equal, ab cd;

1 and 2 are the isotope angles of the lines a, b, truncated by the line c and equal, a b;

5. AC bisects DAB, then 2= 1= 3, 2 and 3 are the internal error angles of the straight line AB and CD truncated by the straight line AC, ba cd;

Always the same edge, there is 5a-a=n*360° solution a=n*90° and because of 180°

Because the angle 5a has the same start edge and the same end edge as a, 5a is greater than a 360-degree integer multiple of a and is set to n

5a-a=n*360, so a=n*90

Because 180°

Because of condition two, and because of condition one, a+5a=360°.

The solution yields a=60°.
