The sum of measures of the interior angles of the octagon 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 octagon that has eight sides. So,
Now, use the polygon interior angles sum theorem to find out the sum of measures of the interior angles of the octagon:
Conclusion:
Hence, the sum of measures of the interior angles of the octagon is
