A 200Ù resistor, 40.0mH inductor and a 2.00ìF capacitor are connected in series with a 120V rms source at 1000 Hz. What is the phase angle of this circuit?

Z= R + jXl  jXc
so figure Xl and Xc, those are just formulas.
then the angle...well...I assume you mean the angle between current and voltage...
Figure Z=Zmagnitude@angle
where angle= arctan(XlXc)/R
then I=(V@0)/Z@angle= =(V/Zmagnitude)@(angle)
and I suppose you are just interested in the negative of angle.
