Question

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

To find the sum of the interior angles of a polygon, you can use the formula:

\[
\text{Sum of interior angles} = (n - 2) \times 180
\]

where \( n \) is the number of sides in the polygon.

For a hendecagon, which has 11 sides:

\[
\text{Sum of interior angles} = (11 - 2) \times 180
\]
\[
= 9 \times 180
\]
\[
= 1620
\]

Thus, the sum of the interior angles of a hendecagon is \( \boxed{1620} \) degrees.
