Yes the Pythagorean theorem would be an easy way to find out. google the laws of right triangle and it will tell you the ratio the sides need to be, so on and so forth. Upvote 0 Downvote

However I question my own assumption based on ass rule being nonexistent. I really never like to assume so I would do the math. It takes 25 secs to do the math, why not. Upvote 0 Downvote
