Answer 1

58.85°

Explanation:

You want to know the measure of the angle in the right triangle that has hypotenuse 29 and adjacent side 15.

Cosine

The cosine function relates angles and sides by ...

Cos = Adjacent/Hypotenuse

cos(x) = 15/29

The inverse function is used to find the angle value:

x = arccos(15/29) ≈ 58.85°

The value of x is about 58.85°.
