Instructions: Find the interior angle sum for the following polygon.

From the figure, we can deduce:
Number of sides of the polygon = 12 sides
Let's find the sum of the interior angles of the polygon.
To find the sum of the interior angles, apply the formula:
[tex]S=(n-2)*180[/tex]Where:
n is the number of sides = 12
Thus, we have:
[tex]\begin{gathered} S=(12-2)*180 \\ \\ S=10*180 \\ \\ S=1800^o \end{gathered}[/tex]Therefore, the interior angle sum for the given polygon is 1800 degrees.
• ANSWER:
1800°
