I know I have to use Kirchoffs law but how would I apply it to this question. I honestly have no idea where to start.

hey brojas, welcome to physicsforums dude. (I'm guessing a guy from the bro-like name).
mm, try writing down the equations for Kirchoff's laws, and seeing how the quantities might be related to the quantities in the diagram.
