A point P having coordinates (-0.6561,-0.7547), lies on the terminal arm of an angle theta in standard position on a unit circle. Sketch this situation and determine the value of theta in degrees.
---------------
The point is in the 3rd quadrant.
The reference angle is tan^-1[-0.7547/-0.6561] = 48.997 degrees
-------------
Therefore theta = 180 + 48.997 = 228.997 degrees
