Spoiler: I got 20 degrees. Anyone else?

I got the same answer as you Sanchek.

Math problems make my head hurt....

i got the same number, and I hate you for making me do that.

well sure you all got x ... the trick is getting x without a protractor

Who used a protractor? That would kind of defeat the point of the whole thing.

was kidding ;) thanks for the edit ... wasn't thinking.

geometry was my favorite math class in high school because it was like solving riddles every day instead of busy work.

I added in lines to form right angles, to figure out a couple. Thats as far as i went.

You almost have to draw the triangle out. There's no way I would have known that some of my lines perfectly intersected at convenient points had I not drawn it out. Made it 100x easier to be honest.
