Use reference angles to find the exact value of the following expression. Do not use a calculator. sin(-150°) Determine the reference angle for -150°. The reference angle is °. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. sin(-150°) = (Simplify your answer. Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression.) B. The answer is undefined.

00:01 Okay, so before we jump into this, let's recall the degrees in my unit circle.
00:04 So the positive x -axis is zero degrees, positive y is 90, 180, 280, and one whole revolution around is 360.
00:14 So secant, recall that secant is the reciprocal identity of sine, or excuse me, cosine.
00:23 So let's say, 195 is in the third quadrant.
00:29 So then what is cosine in the third quadrant? well, cosine, my x value is negative.
00:34 So this would mean that i have to find a angle that's equal to secant with a positive acute angle.
00:44 What is an acute angle? an acute angle means an angle that is less than 90 degrees...
