Explanation / Answer

The unit vector for F1 is
u = cos60 i + cos135 j + cos60 k = 0.5 i -0.71 i + 0.5 k
We know the vertical component of F1 is 200N, so
F1 = 200 i - 283 j + 200 k
The y-component of the 800lb force is (4/5)800 = 640 lb
and the x-component is (3/5)(-800lb) = -480 lb.
Then to be in equilibrium along the x-axis, F2 = 280 lb.
