Consider the angle shown below with an initial ray pointing in the 3-o'clock direction that measures 0 radians (where 0 < 0 < 2n). The circle's radius is 3 units long and the terminal point is ( – 1.72, – 2.45). 2 -2 -1 2. (-1.72, -2.45) a. The terminal point is how many radius lenghts to the right of the circle's center? h = radii Preview b. Then, cos-'(h) Preview c. Does the number we get in part (b) give us the correct value of 0? ? d. Therefore, 0 = Preview 2.
