Question

rewrite sin 29° in terms of its cofunction. sin 29° = (type an exact answer. simplify your answer. type any angle measures in degr in your answer.)

Explanation:

Step1: Recall co - function identity

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

Step2: Substitute \(\theta = 29^{\circ}\)

Substitute \(\theta = 29^{\circ}\) into the identity \(\sin\theta=\cos(90^{\circ}-\theta)\). Then \(\sin29^{\circ}=\cos(90^{\circ} - 29^{\circ})\).

Step3: Calculate the angle

Calculate \(90^{\circ}-29^{\circ}=61^{\circ}\). So \(\sin29^{\circ}=\cos61^{\circ}\)

Answer:

\(\cos61^{\circ}\)
