angle is tan^-1=xL/r,
r<1forangle0-45

Let us assume resistance is infinity than tan-(xl/infinity) that is tan-(0) so it is zero. and in second case assume r=xl than tan-(1) that is 45 degree.

So answer is 0degree and 45degree

z^2 = r^2 + xl^2.

According to Pythagoras theorem,
h^2 = b^2 + p^2.
angle = tan^-1(xl/r).

Then, we get the answer.
