Resistors in AC Circuit

Hey guys, I have a problem with a textbook question.

I have a series AC circuit, with 4 resistors.

Here are the values:

AC Source = 30V Peak
R1 = 1.0 k-Ohm, 16V Peak-to-Peak Drop
R2 = 5V RMS drop, no resistance value
R3 = no values given
R4 = 560 Ohms

I'm asked to find the RMS value of R3. I'm having trouble with the appropriate equation(s) I have to use.

Thanks a lot for the help.
