@ganeshie8 so I'm pretty sure I understand how to do the problems like the one I just asked you but this is something I've never seen before and I'm confused as an expletive.

Oh, you can? Alrighty gimme a moment.

12^2 + 13^2 = 313.

anonymous · Answer

I feel I might have missed a step or something. I also don't really understand, now that I started doing this, how anything I could get from the pythagorean theorem would give me the answer to this?

Oh wait I found an explanation for it elsewhere. I got the answer right :) Thanks though.
