Why will we not use the y component of F2 Force?

How come for F2x, you don’t do 200cos30 (6sin30 + 6)?

i have another solution
first i split the force F1 into 2 along the x and y axes
then we have Mr0 = +F2.sin60.6 - F1x.sin60.6 + F1y(6+cos60.6) (+ if the Force turn back clockwise and vice versa)
