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

Question

Accepted Answer

# Explanation:
## Step1: Identify the number of sides
A nonagon has $n = 9$ sides.
## Step2: Apply the polygon angle - sum formula
Substitute $n=9$ into $(n - 2)\times180^{\circ}$.
$$
\begin{align*}
&(9 - 2)\times180^{\circ}\
=&7\times180^{\circ}\
=&1260^{\circ}
\end{align*}
$$

# Answer:
$1260^{\circ}$
