question 18 of 25
which equation describes the sine function for a right triangle?
a. $\sin(\theta)=\frac{\text{adjacent}}{\text{hypotenuse}}$
b. $\sin(\theta)=\frac{\text{hypotenuse}}{\text{adjacent}}$
c. $\sin(\theta)=\frac{\text{opposite}}{\text{hypotenuse}}$
d. $\sin(\theta)=\frac{\text{opposite}}{\text{adjacent}}$

Explanation:

Recall the trigonometric ratio definitions for a right - triangle. The mnemonic SOH - CAH - TOA is used. SOH stands for Sine = Opposite / Hypotenuse.

Answer:

C. $\sin(\theta)=\frac{\text{opposite}}{\text{hypotenuse}}$
