Question

which of the following is equivalent to \\(\sin 37^{\circ}\\)? (1 point) \\(\cos 37^{\circ}\\) \\(\cos 53^{\circ}\\) \\(\sin 53^{\circ}\\) \\(\sin 63^{\circ}\\)

Explanation:

Step1: Use co-function identity

Recall $\sin\theta = \cos(90^\circ - \theta)$

Step2: Substitute $\theta=37^\circ$

$\sin37^\circ = \cos(90^\circ - 37^\circ) = \cos53^\circ$

Answer:

B. cos 53°
