Calculating Phase Shift for a Series RC Circuit

[map7s]

Homework Statement

A resistor of 362 Ohms is connected in series with a capacitor of 50.0 µF capacitance. A sinusoidal signal of f = 11.7 Hz experiences an impedance of 452.836 Ohms. Find the phase shift between the current and voltage at f = 11.7 Hz.

Homework Equations

I tried using the equation tan = (Xc)/R

Xc=1/(wC)

w=2(pi)f

Z=sqrt(R^2+(Xc)^2)

Where are you stuck exactly?

Well, I used all four of those equations (specifically the first one b/c the question is asking for the angle), but when I plugged in my answer, it was wrong.

tan=(Xc)/R
theta=tan^-1(Xc/R)=37 degrees

Hmmm, let me read it again.
