I had a question on a test....and Im trying to figure what is wrong.....it seems easy...so what am i missing?

What is the phase angle, in degrees, when you divide 62 at an angle of 97 degrees by 18 at an angle of 52 degrees?

I came up with 45.....but the answer said 79?

I thought all you did was subtract...97-52?

Hi Jason03!

Looks like they meant 52 at an angle of 18 degrees!

Actually you ought to have your teacher give tiny-tim the extra points. He guessed the fault in the question.

complex points

Hi Ouabache!

Jason03 can have the real points, and I'll have the imaginary points!
