+5478 There is a formula for calculating the sum of the interior angles of a polygon : $${\mathtt{S}} = {\mathtt{180}}{\mathtt{\,\times\,}}\left({\mathtt{n}}{\mathtt{\,-\,}}{\mathtt{2}}\right)$$ where s is the sum and n is the number of angles in the polygon.
Using this formula, find the sum of a 7-sided polygon (septagon):
S = 180 (7-2)
S = 180 * 5
S = 900 degrees.
