Question

Can someone please help me solve all these questions!! URGENT!

Answer 1

I don't have the time to sort them out for you, sadly, but, I can provide you with some steps for each.

1) That can only be solved with the Pythagorean theorem :

$x {}^{2} = 8 {}^{2} + 15 {}^{2}$

2) That also looks like it can be simplified with the Pythagorean theorem.

3) The unknown side with the "\" on it is equal to

$8 \sqrt{2}$

then it can be simplified massively with the Pythagorean theorem.

4) Since that triangle's total is 180°, and since we know that one side is 90°, the other two (assuming they're equal) have to be 45°, respectively. Knowing that you can find

$\sin(45)$

then, all you have to do is find x (see below for more details)

5) to find x, you can first find

$\cos(60)$

and then find x: (done similarly with triangle 4)

$\cos(60) = \frac{x}{ 4\sqrt{3}}$

Just gonna leave the rest for you. Have a nice day!

Answer 2

1. x=17
2. x=11.79
3. x=16
4. x=? Sorry
5.x=3.464 or 2 square root 3
6.x=11.547
Hope this helps:)
