Complex Impedance: Solve Homework Problem

[zcus05]

Homework Statement

In a circuit consisting of a capacitor (Voltage across is 3.2V) and a 47$$\Omega$$resistor (Voltage across is 4.65V), with a current of 0.0989A and a phase difference between the two voltages being 90', what is the complex impedance for the circuit?

Unsure of how to work this out, the stated values are ones I have worked out and may not necessarily be useful to this problem.

Thanks a ton, I think I get it now, had to brush up on a bit of my old algebra notes.
