I am so frigging old. But if you just had a ruler or compass you could figure it out easily by elimination. Isn't there a formula in geometry that lets you figure out the angles in an isosceles triangle.?

I just divided 360 by the number of angles 12 =30x2=60

Exactly my thought process

360 in a circle, twelve sides......

Ha! I figured it out! The area in question is part of an equilateral triangle!

hard to believe there is any controversy over this question. the answer was obvious before you finished reading the question. which usually means you should read over the question again.

My IQ's only in the 120 range because I rebelled against math early on. "Why would you ever take my word for it over a computer?"

Hahahaha. I'm old enough to remember using slide rules and log tables, where you had to know the answer before you did the final calculation. It's worked out well for me, I consider myself mathematically literate and able to think for myself instead of taking someone's or something's word for it.
