What should I do!! How do you write this question? Online, etc., urgent !!!

I can see that you still want to reconcile with him, I think there must be a reason why his attitude towards you has become cold, but everyone will have their own reasons for not wanting to share with others, he said that he wants to study hard, maybe this is indeed what he really thinks now, or maybe it is just an excuse for him to hope that you can give him some space, but no matter what the real reason is, one thing is for sure, he has begun to perfunctory you and does not want to communicate with you. What you have to do now is not to blindly complain, and not to simply see him become cold and superficial, let alone to make noise, question him, etc., these are irrational practices, not only will not play any role, but will make him annoy you more and widen the distance between you. You should give him a little more understanding and support, you can try to give him more care, such as tentatively asking him if he has encountered any difficulties in life and study, whether there are any troubles that have caused him trouble recently, etc., let him know that you are the person who cares about him the most, the person who can share his happiness and sorrow, try to open his heart knot, let him be honest with you.

As long as you can impress him, make him willing to communicate with you, share his joys, sorrows, and sorrows, tell you what he really thinks, find out the real reason why he has become cold to you, and then prescribe the right medicine, I believe that you can completely get out of the current predicament. I hope my humble opinion will help you a little bit, bless you!

So what do you want to put in the first place? Don't be him. If you put things like making yourself more perfect in the first place, live yourself, and he will put you first!

Can't rush and when you get to a higher height, ask yourself what it is when he is? He is now snubbing you and focusing on his studies because he wants everything better. Stay where you are and cry or run to the front and wait, the choice is yours.

He said he felt it was time to put his studies first.

This kind of thing is farting.

If it really can't be retained, then the long pain is better than the short pain, otherwise the last person to hurt is yourself.

The above is an answer, and so on, such as 165 +30

1.（x+2）²-x²=32，x=7

2.Drawing, the area of the extra 2 rectangles is 32=2 (2x+2).

The school conducts group gymnastics performances, and the number of boys accounts for 40. If there are 100 people in the performance, then there are (40) boys, and if there are 200 people, then there are (80) boys.

201 parts = 553 parts = 95% = 19 parts of 20 =

The first empty space in the second question is: 40 people, and the second empty space is: 80 people.

Set the first pile with x tons, the second with 105-x tons.

1-3/4）x+（1-1/3）（105-x）=3x/4x/4+2（105-x）/3=3x/4

2（105-x）/3=x/2

4（105-x）=3x

420-4x=3x

7x=420

x=60105-x=105-60=55 tons.

A: The first pile has 60 tons and the second pile is 55 tons.

Let the first pile have x tons and the second pile has y tons.

From the title, two equations can be listed as (1-3 4)x +(1-2 3)y =3 4 xx+y=105

The solution is up to you

The first pile has 105 tons, the second has 0 tons.

There are two scenarios when CE is a right-angled edge.

The third case table is more complicated, and CE is the hypotenuse. (Here I want to use the sine theorem and trigonometric functions, I don't know if the landlord has learned it).

Answer: (1) B2+C2=A2+ 3BC

b^2+c^2-a^2=√3*bc.

cosa=(b^2+c^2-a^2)/2bc=√3/2,a=∏/6.

and sinasinb=cos 2(c 2), 1 2*[cos(a+b)-cos(a-b)]=(cosc+1) 2, Note: obtained by using the formula of product sum difference and cosc=2cos 2(c 2)-1, two formulas), there is.

cos(a-b)-cos(a+b)=cosc+1,cos(a-b)-cos(a+b)=-cos(a+b)+1,cos(a-b)=1,a-b=0, i.e., a=b=6,c=180-(a+b)=2 3.

2)√7/sin30=ab/sin(180-30-15)ab=2√7*sin45=√14.

Let , the triangle abc, the height on the edge of ab is h, h=tan30*14 2= 42 6

Area of ABC = 1 2 * ab * h = 7 3 6
