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.
; for example, each edge of a hexagon subtends an angle of 360 / 6 60 degrees at its center. The interior angles of an n-gon are the same and equal 180 2 /nn degrees; for example, the interior angles of a square are 180 4 2 / 4 90 180 8 2 / 8 135 degrees and of an octagon are degrees. The inte-rior and central angles are supplementary; they sum to 180
