Answer to Problem 11.5.4EP
The sum of measures of the interior angles of the pentagon is
Explanation of Solution
Given:
Convex
Concept Used:
The polygon interior angles sum theorem is given by the following expression:
Where,
Sides of polygon:
Calculation:
The name of the given polygon is pentagon that has five sides. So,
Now, use the polygon interior angles sum theorem to find out the sum of measures of the interior angles of the pentagon:
Conclusion:
Hence, the sum of measures of the interior angles of the pentagon is
