An illustration of a hendecagon with the vertices labeled upper A, upper B, upper C, upper D, upper E, upper F, upper G, upper H, upper I, upper J, and upper K clockwise from the top.

Find the sum of the interior angles of a hendecagon (11-sided polygon).

(1 point)
The sum of the interior angles of a hendecagon is ___°

Answer 1

The sum of the interior angles of a hendecagon can be found using the formula: (n-2) * 180, where n is the number of sides of the polygon.

For a hendecagon with 11 sides, the sum of the interior angles would be (11-2) * 180.

Simplifying the equation, we have (9) * 180 = 1620.

Therefore, the sum of the interior angles of a hendecagon is 1620°.
