Answer:
540 degrees
Step-by-step explanation:
The formula to find the sum of interior angles in any polygon is the following:
[tex]S=180(n-2)[/tex]
Where (n) represents the number of sides in the polygon. In this case, the polygon has (5) sides, therefore substitute (5) in place of (n) and solve;
[tex]S=180(n-2)\\\\S=180(5-2)\\\\S=180(3)\\\\S=540[/tex]
