Answer:
Sum of the interior angles = [tex]540^{o}[/tex]
Step-by-step explanation:
Formula of a polygons interior angles sum is [tex](n-2)180^{o}[/tex]
n = the number of sides
Polygon with five sides is labeled as pentagon.
[tex]((5)-2)180^{o}\\ (3)180^{o}\\540^{o}[/tex]
Sum of a pentagon's interior angles are 540 degrees.
