Question

find a cofunction with the same value as the given expression. sin 24° select the correct choice below and fill in the answer box to complete your choice. (simplify your answer. type any angle measures in degrees. do not include the degree symbol in your answer.) a. sin 24° = cot □° b. sin 24° = tan □° c. sin 24° = csc □° d. sin 24° = cos □° e. sin 24° = sec □°

Explanation:

Step1: Recall co - function identity

The co - function identity for sine and cosine is $\sin\theta=\cos(90^{\circ}-\theta)$.

Step2: Substitute $\theta = 24^{\circ}$

When $\theta = 24^{\circ}$, we have $90 - 24=66$.

Answer:

D. $\sin24^{\circ}=\cos66^{\circ}$
