Answer:
The sum of the interior angle is 108°
Step-by-step explanation:
To find the sum of the interior angle, you need this equation:
[tex]\frac{180(n-2)}{n}[/tex] (The variable [tex]n[/tex] represents the number of sides does a shape have).
-Count the sides of the shape:
The following polygon shown, has 5 sides.
-After you have the number of sides of the polygon, use the number of sides for the equation and it will be written as:
[tex]\frac{180(5-2)}{5}[/tex]
-Then, you solve:
[tex]\frac{180(5-2)}{5}[/tex]
[tex]\frac{180(3)}{5}[/tex]
[tex]\frac{540}{5} = 108\textdegree[/tex]
So, the sum of the interior angle is [tex]108\textdegree[/tex].
