Question

what is the sum of the interior angles of a heptagon?
polygon angle sum formula: $(n - 2)180^{circ}$

Explanation:

Step1: Identify the number of sides

A heptagon has \(n = 7\) sides.

Step2: Substitute into the formula

Using the formula \((n - 2)\times180^{\circ}\), substitute \(n = 7\).
