statics problem

The Attempt at a Solution

So basically what I am trying to do is break up the problem and solve for segment CD then solve for segment DE. But I am getting different answers compared to my friends.Im not including any forces at CD when i solve .Is there an external force of AC on CD and Force BD on CD.Please can someone explain. basically when i can solve for E i solve for A using moment at A while taking the whole frame as a whole.

My Attempt:For the equilibrium of segment CDX component:FBD cos(90) - FAC cos(90) = 0Y component:FAB sin(90) + FBD sin(90) - FAC sin(60) - FDE sin(30)= 0Moment about AFAB x AB + FBD x BD - FAC x AC - FDE x DE = 0For the Equilibrium of segment DE X component:FAC cos(60) + FDE cos(30) = 0Y component:FAC sin(60) -FDE sin(30) = 0Moment about EFAC x CE - FDE x DE = 0
