Within the boundaries of Rocky Mountain National Park, more than 100 peaks rise above 11,000 feet in altitude, including Longs Peak at 14,259 feet. These amazing mountains cradle the Estes Valley, providing residents and guests with incredible beauty and inspiration.
Hexagon: 720. Heptagon: 900. In general: n-agon: (n-2) * 180. With seven angles in a heptagon, each angle is 128.581427... degrees. The total is 900 degrees. Despite what others have posted here, the answer is *not* 360 degrees in every polygon. Even if you don't know the right answer for a heptagon, intuitively you know that a triangle is 180, a square is 360.
the formula for calculating degrees of any polygon is: 180(n-2) where n is the number of sides a decagon has 10 sides so it is: 180(10-2) The answer is 1440 degrees. You mean, how many degrees in one of the interior angles? Assuming this is a regular decagon, you can break it up into 10 isocelese triangles with 180/10 = 18 degrees in one angle, with the other two angles adding up to 180 - 2*18 = 144 degrees.
