 In this video, we provide the solution to question number five for the practice exam number one for math 1060. We're given the angle theta equals 195 degrees and we're asked to compute the reference angle which we're gonna call theta prime in the situation. A reference angle is always gonna be in the first quadrant. It needs to be between zero and 90 degrees if we're doing degree measure like we are in this question right here. So if you have 195 degrees, notice that 195, it's less than 270 degrees but it's greater than 180 degrees. So our angle here is gonna terminate in the third quadrant. So we need to find the reference angle, we need to subtract 180 from it so we get something between zero and 90 degrees. So we're gonna take 195 degrees to track from it 180 degrees and that's gonna then give us 15 degrees and so the reference angle of theta would be choice A, 15 degrees.
