Homework Equations

V=IR
V(C)=X(C)*R

The Attempt at a Solution

I'm having trouble with number two. I tried finding Z from the frequency and then calculating the current and mutiplying that by X(C) and got 92.9

a little typo is that I wrote V(R) twice in the diagram. The top one is V(L)

ohhh nvm from looking at the figure I realized how to do it. By using the triangle at the bottom!
