I m going to crash!! Help! Let s not get worse!!

I'm dizzy. You have a girlfriend yourself, and you like your cousin.

Besides, you are close relatives, and it is not right to be reasonable.

And besides, your girlfriend is so nice.

If it were me, I would never have been able to do it.

She must be a generous and decent person.

You might as well think about cherishing your current girlfriend.

What to do? Don't you cherish having such a good wife? Love your wife well. She really loves you. It's also really great. If I could find such a good girlfriend, I'm thankful.

As a woman, it is already rare to be able to show such a large measure, without blaming you, will you still be cranky, will you be embarrassed to think about anything else?

Love your girlfriend so well, buddy! There are too many things in the world that make you depressed, they are all fans of the authorities, and the bystanders are clear, and you still have a layer of family affection for your cousin, and the family affection and your fantasies about her make you even more unable to extricate yourself. Take the time to downplay it all!

Cherish your girlfriend and your cousin well, and don't wait until it's too late the day you lose your lovely girlfriend!! 1

Be kind, and don't step on multiple boats. You can care about your cousin, but be mindful of who you are and the angle you care about. And at the end of the contradiction and chicken and egg fighting.

Leave her, don't pay attention to her business. Time will be the medicine that heals.

Let the purchase price x, then the original selling price is, and the reduced selling price is multiplied by equals, then the interest rate is (divided by x equals, that is, 4%.

a+c=120°，c=120°-a

by the sine theorem.

a/sina=c/sinc

a=(3^(1/2)-1)c

sina=(3^(1/2)-1)sinc

3^(1/2)+1)sina=2sin(120°-a）=3^(1/2)cosa+sina

sina=cosa

a=45° or a=135° (rounded).

So a=45°

f(x)=cos2x+asinx

1-2sin^2x+asinx

2(sinx-a 4) 2+1+a 2 2x belongs to [30 degrees, 90 degrees].

1/2<=sinx<=1

When 1 2 < = a 4< = 1.

f(x) has a maximum value of 1+a2 2=3

a=201.

The maximum value of f(x) is a=3

a=3 (rounded).

So a=2,c=2 (3 (1 2)-1)=3 (1 2)+1s abc=acsinb 2=2*(3 (1 2)+1)*(3 (1 2)) 2 2=(3 (1 2)+1) 2

Please feel free to use it.

If you have any questions, please feel free to ask.

Neither will I! Pray to the Great God! Tell me about it, too.

First of all, we need to set the equation to solve:

Set the candy of the adjusted Weimin supermarket to Y

Set the candy in Xinglong Supermarket after the adjustment is X

And two supermarkets candy and for.

System of equations: x y=2

Now it's time to solve the equation.

First, substituting into solves x= y=

In the end, it is necessary to figure out how much to transfer from Weimin Supermarket to Xinglong Supermarket.

This is a simple equation problem.

Set up x kilograms of candy from the private supermarket to Xinglong supermarket.

Get 2 (solution x=30.)

Isn't this easy? You can set up a supermarket with candy Y kilograms, then Xinglong Supermarket has candy 2Y kilograms. Then y+2y=

x= kilograms.

It's 30 kg.

It's better to solve this kind of question by yourself, tell you the answer, you still don't know how to calculate, what to do in the exam.

Unraveling the transfer of x kilograms of candy.

2 (3x=x=A: Remove kilograms of candy.)

You can set up a private supermarket with x kg of candy, then Xinglong supermarket has 2x kg of candy. then x+2x=

The solution is x = kilogram, so when the supermarket transfers 30 kilograms of candy to Xinglong supermarket, the candy in Xinglong supermarket is twice as much as the candy in the supermarket.

30 kg, it must be the answer! I've done the math.

Transferred 30 kilograms of candy to Xinglong Supermarket, and the candy in Xinglong Supermarket was twice as large as the candy in Weimin Supermarket.

( x=30.)

So 30 kilograms should be transferred to Xinglong supermarket.

Let the candy transferred from the Weimin supermarket be x2*(

Adjust the kilogram to Xinglong supermarket.

Do the math yourself, it should be easy to calculate

37.6 is twice the size of Weimin Supermarket.

(1) If b=60° is known, then c=120°-a; sina sinc=a c= 3-1

Therefore, sina sin(120°-a)= 3-1, sina = ( 3-1)sin(120°-a) = ( 3-1) (sin120°cosa-cos120°sina) = ( 3-1) (3 2cosa + sina).

→sina=cosa

Get a = 45°

2）f(x)=cos2x+asinx=1-2sin²x+asinx=1+(a²/8)-2[sinx-(a/4)]²1+(a²/8)=3

Get a=4[At this point, sinx-(a 4)=0, x=2, is eligible.] ]

Then s abc = acsinb = a·a ( 3-1)·sin60° = 4 [4 ( 3-1)] 3 2 = 6 + 2 3
