Question

What is the sum of the interiorangle measures of a polygonthat has 7 sides?Sum = [?]°Hint: Sum = (n-29180Enter

Answer 1

A polygon with 7 sides is a heptagon.

Given:

number of sides = n = 7

The sum of interior angles in a polygon is given by;

$\begin{gathered} \text{Sum}=(n-2)180 \\ \text{Sum}=(7-2)\times180 \\ \text{Sum}=5\times180 \\ \text{Sum}=900^0 \end{gathered}$

Therefore, the sum of the interior angles of a polygon with 7 sides is 900 degrees.
