Question

what is the sum of the interior angles of a heptagon?
polygon angle sum formula: (n - 2)180°

Explanation:

Step1: Identify the number of sides of the polygon

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

Step2: Substitute \(n\) into the formula

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

Step3: Calculate the result

First, \(7-2=5\). Then \(5\times180^{\circ}=900^{\circ}\)

Answer:

\(900^{\circ}\)
