the question is have is  solve z1/z2 in polar form.  z1= 3-j2 and z2=-4+j2.  i solved that z1 polar is 3.61e^-j33.69degrees.  z2 polar is 4.47e^j153.43 degrees.  so i get 0.81 for magnitude.  for the angle I take -33.69degrees-153.43 degrees.  I get -187.12 degrees. Per my calculator I get 0.8062 so mag is correct but the angle is 172.875.  adding or subtracting 180 doesn't get me there. Where am I going wrong?
