Got this wrong. please help and show work then round the final answer to 3 sig figs.

The shelf bracket is subjected to the force F = 279 Newtons
at an angle = 24.8°. Compute the moment (in N-m) that
this force exerts about each of the two attachment points
(screw locations in the figure). Take counterclockwise
moments to be positive.
