haha sounds good. I'll buy ya a beer sometime I ever go to a meet sometime haha.

First I made a trapezoid with the long side equal to 2R, and the two sides equal to R. Then I created a 30/60/90 triangle and solved for the short side of the trapezoid. Then I found an equation to find the radius of a circle with a triangle inside in. Kinda hard to explain, but eventually my buddy showed me the way you did it and that's much quicker and simpler. Props on being smart even when you're drunk lol.
