(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Let A be the area of a polygon with n equal sides inscribed in a circle with radius r. By dividing the polygon into n congruent triangles with central angle 2pi/n, show that A = [tex](\frac{1}{2})nr^{2}sin(2(\pi)/n)[/tex]

2. Relevant equations

Area of a circle = pi x r^2

Area of triangle = (base x height)/2

sin x = opposite/hypotenuse

3. The attempt at a solution

My attempt is in the attached word document. I spent over an hour trying to use the latex/equation stuff, and normally I know how to use it, but it kept putting in stuff that I wasn't actually typing. Every line would just show up as something random.

I apologize in advance.
