How many degrees is in octadecagon?
An octadecagon has 18 sides. To find the sum of the interior angles of a polygon, you can use the formula ((n - 2) \times 180), where (n) is the number of sides. For an octadecagon, the sum of the interior angles is ((18 - 2) \times 180 = 2880) degrees. Each interior angle of a regular octadecagon is (2880 \div 18 = 160) degrees.
