STEP 1

Assumptions1. The polygon has11 sides. The formula for the interior angle sum of a polygon is $(n-) \times180$ degrees, where $n$ is the number of sides the polygon has

STEP 2

We need to find the interior angle sum for a polygon with11 sides. We can do this by substituting $n =11$ into the formula.
$$Interior\, angle\, sum = (n-2) \times180\, degrees$$

STEP 3

Substitute $n =11$ into the formula.
$$Interior\, angle\, sum = (11-2) \times180\, degrees$$

STEP 4

Calculate the value inside the parentheses.
$$Interior\, angle\, sum =9 \times180\, degrees$$

Calculate the interior angle sum.
$$Interior\, angle\, sum =9 \times180 =1620\, degrees$$The interior angle sum for a polygon with11 sides is1620 degrees.
