Square root of (a^2+b^2) = Square root of 72 = 8.48.
tan-1 (b/a) = tan-1 (6/6) = 45.
tan-1 (b/a) = tan-1 (6/6) = 45.

How does that 8.48 has come? Can anyone help me in answering this?

Alpha = tan-1(b/a).
Its alpha = tan-1(6/6).
= tan-1(1) = 45.
Its alpha = tan-1(6/6).
= tan-1(1) = 45.

If R and Xc are equal then the angle always 45 in RC circuit.

x=a+jb
|x|=sqrt(squar(a)+squar(b))
angle(a)=tan-1(a/b)
|x|=sqrt(squar(a)+squar(b))
angle(a)=tan-1(a/b)

@Sadananda.
Its not tan-1(a/b) its tan-1(b/a).
Its not tan-1(a/b) its tan-1(b/a).

Yeah, that's correct @Malleswar.
