I solved the problem the way I think it's suppose to be solved, but the numbers I'm getting seem way too low, so I screwed up somewhere. Is my trigonometry correct in this equation?
MD = (0.8)TBEsin51.3 + (1.2)TFCsin68.2 = 0
Problem is here,

I'm looking at this problem with the top and bottom beams being separate members and doing a FBD of both separately. However I'm unsure about the points where we have tension/compression. Like at point B, do I include a y component...
