Question

Accepted Answer

# Explanation:
## Step1: Recall the formula for the sum of interior angles of a polygon
The formula for the sum of interior angles of a polygon is $S=(n - 2)\times180^{\circ}$, where $n$ is the number of sides of the polygon.
## Step2: Determine the number of sides of the polygon
The given polygon is a pentagon, so $n = 5$.
## Step3: Substitute $n = 5$ into the formula
$$
\begin{align*}
S&=(5 - 2)\times180^{\circ}\
&=3\times180^{\circ}\
&=540^{\circ}
\end{align*}
$$

# Answer:
$540$
