Tricontagon
From Wikipedia, the free encyclopedia
In geometry, a triacontagon is a polygon with 30 sides. The sum of all the angles in a triacontagon sums 5040 degrees. The measure of each angle of a regular triacontagon is 168 degrees, and the area with side length a is given by
- <math>A = \frac{15}{2}a^2 \cot \frac{\pi}{30} \simeq 71.3577 a^2.</math>
[edit] Trivia
A "Michelob Golden" beer can is in the shape of a triacontagon.
