Question

watch the video and then solve the problem given below. click here to watch the video. rewrite cos 33° in terms of its cofunction. cos 33° = □° (type an exact answer. simplify your answer. type any angle measures in degrees. do not include the degree symbol in your answer.)

Explanation:

Step1: Recall co - function identity

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

Step2: Substitute the given angle

Here $\theta = 33^{\circ}$, so $\cos33^{\circ}=\sin(90 - 33)$.

Step3: Calculate the result

$90-33 = 57$.

Answer:

57
