I found total impedance to be 14.23 ohms with an angle of 20.15. Found power factor to be .938
Pretty much stuck at a dead end trying part 2 and 3.

[STRIKE]Can you detail your calculation of impedance and power factor? 14.24 Ohms seems a bit small to me.[/STRIKE]
EDIT: Never mind, my mistake: you have the impedance correct.

What's the magnitude of the voltage supply, E?

Supply voltage or current was not given. Just found out we were supposed to assume a 120v with angle 0 supply.

Okay, so you known the voltage supplied and you know the impedance. You should be able to find the power delivered.
