Answer:
The sum of the interior angle measures of the polygon is 540°
Step-by-step explanation:
The formula of the sum of the measures of the interior angles of a polygon is
∑m = (n - 2) × 180°, where n is the number of the sides of the polygon
In the given figure
∵ The polygon has 5 sides
∴ n = 5
→ Use the formula above to find the sum of the interior angle measures of it
∵ ∑m = (5 - 2) × 180°
∴ ∑m = 3 × 180°
∴ ∑m = 540°
∴ The sum of the interior angle measures of the polygon is 540°
