Sagot :

Answer:

D

Step-by-step explanation:

Using the cosine ratio in the right triangle.

cos66° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{13}{x}[/tex] ( multiply both sides by x )

x × cos66° = 13 ( divide both sides by cos66° )

x = [tex]\frac{13}{cos66}[/tex] ≈ 32.0 ( to the nearest tenth )
