I have to find the forces in the members marked with an x.
2. The attempt at a solution
I found the support reactions, but I'm not sure if I need them. Should I try to find the...
I completely missed that. Thank you.
After taking the moments for each side is it as simple as solving Cx in terms of Cy or vice versa and finishing it up?

I am trying to find the support reactions at A and B.
I separated the frame at the hinge(call it C) into two parts and took the moment equation about point A.
This gave me: \SigmaMa = -60(25) - 62.5(12.5) +...
