The sum of the interior angles of any polygon can be found using the formula:
Sum of interior angles = (n - 2) * 180
where n is the number of sides of the polygon.
For a hendecagon (11-sided polygon), the formula becomes:
Sum of interior angles = (11 - 2) * 180 = 9 * 180 = <<(11-2)*180=1620>>1620
Therefore, the sum of the interior angles of a hendecagon is 1620 degrees.
Find the sum of the interior angles of a hendecagon (11-sided polygon).
