If FB = 35lb and FC = 50lb , determine the resultant moment about the bolt located at A (Figure 1) .?

My work:

Fbcos(25)*2.5 + Fccos(30)*(2.5+.75)= 184 (approx)

I thought this would be too easy, and indeed it wasn't the right answer....

Help! :)

    Your LHS is correct, but you got the wrong result. I get 220 ft·lbs.
