Not sure what you are doing with the angles. Both moments act in the x-y plane, so there shouldn't be any [itex]\hat{k}[/itex] involved. The first moment acts in the -x direction ([itex]- \hat{i}[/itex]); the second moment is at a 60 degree angle to the x-axis (find the components of that vector: it will have both an x and a y component).
