22. Find the measure of the indicated angle to the nearest degree.

Answer:
A
Step-by-step explanation:
using the cosine ratio in the right triangle
cos? = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{17}{27}[/tex] , then
? = [tex]cos^{-1}[/tex] ( [tex]\frac{17}{27}[/tex] ) ≈ 51° ( to the nearest degree )
