To find the sum of the interior angles of a hendecagon, we can use the formula:
Sum of interior angles = (n - 2) * 180 degrees
Where n is the number of sides of the polygon.
In this case, n = 11. Plugging this into the formula, we get:
Sum of interior angles = (11 - 2) * 180 degrees
= 9 * 180 degrees
= 1620 degrees
Therefore, the sum of the interior angles of a hendecagon is 1620 degrees.
