Answer to Problem 15CFU
Explanation of Solution
Given information:
Calculation:
We are asked to find the reference angle.
The reference angle is the angle the terminal side makes with the x -axis.
Below is a sketch of our angle.
Since it is quadrant III we subtract 180 degrees from our angle
Since it is in quadrant III we subtract 180degrees from our angle
