Answer:
C. 20.8
Step-by-step explanation:
Reference angle = 32°
Opposite side length opposite to reference angle = 13
Adjacent side length = x
We would apply the trigonometric function, TOA. Which is:
Tan 32 = Opp/Adjacent
Tan 32 = 13/x
Multiply both sides by x
x × Tan 32 = 13
Divide both sides by Tan 32
x = 13/Tan 32
x = 20.8043489
x = 20.8 (nearest tenth)
