The two forces f1 and f2 acting at a have a resultant force of fr= -100lb. determine the magnitude and coordinate direction angles of f2

Two forces F1 and F2 act on the screw eye. The resultant force FR has a magnitude of 125 lb and the coordinate direction angles shown in (Figure 1) . Determine the magnitude of F2. Determine the coordinate direction angle α2 of F2. Determine the coordinate direction angle β2 of F2. Determine the coordinate direction angle γ2 of F2.

I think its c 

Hope this is right
