Question

How do I go about solving this type of problem? I have others like it and want to know the process.

Answer 1

104.1

Explanation:

Use SOH CAH TOA.

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

In this case, the hypotenuse is x, and the side opposite of the 22° angle is 39. Since we have opposite and hypotenuse, we need to use sine.

sin 22° = 39 / x

x sin 22° = 39

x = 39 / sin 22°

x ≈ 104.1
