question 20

Multiple Choice

Use a calculator to calculate the value of $\theta$ from the given identity. $\sin ( - \theta ) = - \sin \theta , \theta = 251 ^ { \circ }$

• A) \( \sin ( - 251 ) = - \sin 251 \approx 0.9755\)
• B) \(\sin ( - 251 ) = - \sin 251 \approx 0.9455\)
• C) \( \sin ( - 251 ) = - \sin 251 \approx - 0.9455\)
• D) \(\sin ( - 251 ) = - \sin 251 \approx - 0.9655\)
• E)\(\sin (-251)=-\sin 251 \approx 0.9655\)
