CPM Homework Help : INT3 Problem 9-45

What are the coordinates of points $P$ and $Q$ on the unit circle at right?

Partial Answer:

$P: \left(\text{cos}\left(50^\circ\right), \text{sin}\left(50^\circ\right)\right)$
$Q: \left(\text{cos}\left(110^\circ\right), \text{sin}\left(110^\circ\right)\right)$

Unit circle, center at the origin, with line segments, from center, to points on circle, one labeled, p, in first quadrant, & one labeled, q, in second quadrant. Central angles, between each segment & x axis, labeled 50 degrees, & 110 degrees.
