Hello everyone!

Vs=2.5/_0° V rms. R1, L, R2, and C are unknown. Load 1 absorbs a a complex power of 100/_45° VA and load 2 absorbs a complex power of 50/_-45° VA. Find R1 in Ω.

I've tried doing multiple calculations that lead me to writing a pile of nonsense/gibberish or absolutely nothing.

Any help would be appreciated!

Well, it's hard to help you spot the flaw in your work or your reasoning unless you show your work and your reasoning.
Done.
I added the complex powers to find the total complex power in the circuit then by using the complex power equals to the voltage squared over the total impedance. I now have the total complex power, and the voltage is given, so by solving for the impedance and taking the real part I get the answer.
