Solving Complex Number Division: 79 Degrees?

[Jason03]

I had a question on a test...and I am 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!

well than that's a good thing..right?...lol...I need to let my teacher know so I can get the extra points...

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

Hi Ouabache!

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

This is too complex for me.
