Question

if you are given the two sides that are not the hypotenuse, which trig function should you use? sine cotangent tangent cosine

Explanation:

In a right - triangle, sine and cosine involve the hypotenuse. Tangent is the ratio of the opposite side to the adjacent side (both non - hypotenuse sides). Cotangent is the reciprocal of tangent. When given the two non - hypotenuse sides, tangent is used as it is defined as $\tan\theta=\frac{\text{opposite}}{\text{adjacent}}$.

Answer:

C. tangent
