Reaction forces at pin joint on a frame

[cs003]

Homework Statement

Basically, I am looking to find the reaction forces at the pin joint on the right side of the structure. I just realized it is not labeled on my diagram, but it is the pin on the link opposite of E. Where the 13 degree angle is measured from.

Homework Equations

I have tried to use the sum of the moments and forces equal to 0, but I am stuck and not sure what to do to solve for the unknowns I need.

The Attempt at a Solution

My attempt at the solution is attached. If anyone could help me just set up the equations I would need to find the reaction forces at the pin at the right end of the structure that would be great.

Thanks!

Your equations all apply to the parallelogram frame as a whole. That means it might as well be a rigid 2D object, in which case there would only be three independent equations available. Indeed, there would not be a unique solution.
After your first three equations, to make progress you need to consider force balances on parts of the frame that are only pinned to each other. That may bring in more unknowns for the internal forces. Keep going until you have as many equations as unknowns.
