Question

I need help, medal will be rewarded, I need to know how to solve this problem!

Find the value of x. Round to the nearest degree.

Answer 1

Do you recall the formulas for sin x and cos x using the
sides of a right triangle: "opposite" "adjacent" "hypotenuse" ?

Answer 2

...........no

Answer 3

You know which side the hypotenuse is, right. Its the side marked 20 in your example.
Pretend like you are sitting on that angle marked with the x.
The "adjacent side" is always the side nearest your angle.
The "opposite side" is always the side that your angle is not touching on the opposite side of the triangle. Is 11 the adjacent side or the opposite side?

Answer 4

Adjacent :)
