Question

2 trig ratios missing sides and angels

Answer 1

Answer:

D

Step-by-step explanation:

Using the cosine ratio in the right triangle.

cos66° = $\frac{adjacent}{hypotenuse}$ = $\frac{13}{x}$ ( multiply both sides by x )

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

x = $\frac{13}{cos66}$ ≈ 32.0 ( to the nearest tenth )
