Question

what is the sum of the interior ang below?

Explanation:

Step1: Recall the formula for sum of interior angles

The formula for the sum of the 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

Counting the sides of the given polygon, we find that $n = 12$.

Step3: Calculate the sum

Substitute $n = 12$ into the formula: $S=(12 - 2)\times180^{\circ}=10\times180^{\circ}=1800^{\circ}$.

Answer:

$1800^{\circ}$
