Question

Find x. Round your answer to the nearest tenth of a degree. x

Answer 1

Answer:

x ≈ 48.2°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos x = $\frac{adjacent}{hypotenuse}$ = $\frac{6}{9}$ , then

x = $cos^{-1}$ ( $\frac{6}{9}$ ) ≈ 48.2° ( to the nearest tenth )
