Question

question what is the sum of the interior angles of an 11 - gon? answer attempt 1 out of 2

Explanation:

Step1: Recall the formula

The formula for the sum of interior - angles of a polygon is $S=(n - 2)\times180^{\circ}$, where $n$ is the number of sides of the polygon.

Step2: Substitute $n = 11$

Substitute $n = 11$ into the formula: $S=(11 - 2)\times180^{\circ}$.

Step3: Calculate the result

First, calculate $11−2 = 9$. Then, $S=9\times180^{\circ}=1620^{\circ}$.

Answer:

$1620^{\circ}$
