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 F 1 and F 2 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 F 2. Determine the coordinate direction angle α 2 of F 2. Determine the coordinate direction angle β 2 of F 2. Determine the coordinate direction angle γ 2 of F 2.
