The Attempt at a Solution
I really don't know what to do here. I've looked through all my notes and book and haven't seen any problems like this (with no angle). Every time I try to rearrange and substitute equations I still end up with 2 unknowns. It would be great if someone could point me in the right direction.[/B]
