How Do You Calculate Voltage and Impedance in AC Circuits?

[MissP.25_5]

Hi again. I just want to make sure I got the answers correct since this is a past year question (received from a senior), I don't have the answers.

Power supply voltage E=10e^(jπ/4) [V]; Current I1=2e^(jπ/4) [A].
The magnitude of current I2 is equals to current I1, but its phase is π/2 slower than I1.
1) Find the voltage V.
2)Find impedance Z.

Show your work.

Yep. Your work looks fine.

Thanks!I am posting a couple more works that I've done. I hope you don't mind checking.
