Question

translate the sentence into an equation or formula. the interior angle sum s of a convex polygon is equal to 180 times the difference between the number of sides of the polygon n and two.

Explanation:

Step1: Identify the key - elements

The interior angle sum is $S$, the number of sides is $n$, and we need to find the difference between $n$ and 2 first.

Step2: Translate the relationship

The difference between $n$ and 2 is $n - 2$, and $S$ is 180 times this difference.
$S=180\times(n - 2)$

Answer:

$S = 180(n - 2)$
