Mechanics: Forces at Equilibrium (resolving forces)

Please help with this question:

The following set of forces is in equilibrium. Find F1 and F2

Ages since i`ve done any mechanics ...(sorry, just got a bad taste in my mouth at that word..) but, isn`t this like , because the verical forces are in equilibrium, you resolve vertically up, then equate to vertically down.. (same horizontally)

...Thank you

Since the forces are in equilibrium, which ever direction you resolve in, the sum of the forces will be zero.

You can resolve horizontally and vertically as Hasufel suggested, and then solve the simultansous equations.

BUT, it would be easier to resolve in the direction of F1, and the direction of F2. Since F1,F2 are prependicular the component of F1 in the direction of F2 will be zero and vice versa, and your equations will be simpler.
