What is the sum of the measures of the interior angles of a 25-ton?

4140°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 25, thus

sum = 180° * 23 = 4140°

Sum of the measures of the interior angles of of a 25-sided polygon is 4140∘

Explanation:

Sum of the measures of all the exterior angles of any polygon, irrespective of its number of sides is always 360∘.
