Question

calculate the sum of the interior angle measures of a polygon with 27 sides. the sum is

Explanation:

Step1: Recall the formula

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

Step2: Substitute $n = 27$

Substitute $n = 27$ into the formula: $S=(27 - 2)\times180^{\circ}$.
First, calculate $27−2$: $27−2 = 25$.
Then, calculate $25\times180^{\circ}$: $25\times180^{\circ}=4500^{\circ}$.

Answer:

$4500^{\circ}$
