Question

match each trig function with its ratio. cosine sine a. $\frac{hyp}{opp}$ b. $\frac{opp}{adj}$ c. $\frac{opp}{hyp}$ d. $\frac{hyp}{adj}$ e. $\frac{adj}{hyp}$ f. $\frac{adj}{opp}$ question help: video > next question

Explanation:

In a right - triangle, the cosine of an angle is defined as the ratio of the adjacent side to the hypotenuse, i.e., $\cos\theta=\frac{adj}{hyp}$. The sine of an angle is defined as the ratio of the opposite side to the hypotenuse, i.e., $\sin\theta = \frac{opp}{hyp}$.

Answer:

Cosine: e. $\frac{adj}{hyp}$
Sine: c. $\frac{opp}{hyp}$
