1. The problem statement, all variables and given/known data Calculate the phasor notation for -43.62+j20.52 My answer is 180 degrees off and I don't know why you add it in this case. I just want to know how to calculate angle, the magnitude I found fine. 2. Relevant equations tan-1(X/R) 3. The attempt at a solution tan-1(20.52/-43.62) = -25.19 degrees That's the answer I get but the answer is 180 degrees plus my result above resulting in 154.8 degrees edit: I'm guessing it may be because it's in quadrant 2 or 3?
