Finding Force in Element D-C of a Truss

[toolpusher123]

Homework Statement

I've solved all but one force. I can't seen to get the force within element D-C. All relevant variables are shown on the pics attached i.e loads, supports, dimensions etc...

Homework Equations

Sum of forces in x=0, sum of forces in y=0, sum of moments=0

Why don't you try applying the same methods that you used to find the forces at joints A and E to either joint C or joint D, this should give the force in the member CD
