2 trig ratios missing sides and angels
ivanzaharov [21]

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 )
