I'm to work out the internal forces in a truss, but I can't get my head around the geometry of the truss itself. I'm starting to think there may have been information on the diagram which I missed. Could I get some directions on how to find x?

I suspect that you are meant to assume the truss is symmetric, and which point I think you have enough data. –  dmckee Oct 20 '12 at 19:27

I was able to reconstruct the geometry with GeoGebra. Look for equidistant triangles.
