Calculate the theoretical forces in members AB, AC and AD of the cantilever truss shown
above as a function of the known load.

I'm having a huge problem with this question. I have an understanding of how to do it but the pictures odd, not sure if it's a typo or what. Basically i thought the points would be at the corners but they're not. So i'm a little confused. Any help would be greatly appreciated.
