Question

Find theta to the nearest tenth of a degree, if theta is between 0 degrees and 360 degrees for sin theta = 0.4649 with theta in quadrant 2

Answer 1

9514 1404 393

Answer:

152.3°

Explanation:

The arcsine function only gives angles in quadrants I and IV. Since this is a quadrant II angle, its value will be ...

θ = 180° -arcsin(0.4649) = 180° -27.7°

θ = 152.3°
