How to find the hypotenuse of a right angled triangle using trigonometry?

It depends on whether you have "Perpendicular" or "base"
If you have perpendicular then, you can use the formula:
sin Ф = P / H

If you have base then, you can use the formula:
cos Ф = B/ H

Hope this helps!

Byou start by adding them all and setting them equal to 180 since that is half of the total degrees in a circle.(2x+8) + (3x-14) + (3x-14) = 1808x-20 = 1808x = 200x = 25

The total would be 40.53
