Homework Equations
Cosine rule
F = √(F_{x}^{2} + F_{y}^{2})
The Attempt at a Solution
I tried to calculate the force components in the x and y direction for both and got two expressions for R (one from each system) and made them equal each other. However I have two unknowns (F1 and F2) when I try this and am unsure how to proceed :/
