Hello, I was wondering if someone could explain part of the solution to this problem for me.

To the right is the Free Body Diagram of Disk E, and I can draw the forces on there well enough. But I really do not understand how they obtained that triangle for N' (1-5-√24). I know this is the force of disk D acting on disk E, but that's about it.
