Recall the Polygon Angle-Sum Theorem, which states that the sum of the measures of the interior angles of a regular n -gon is (n-2)* 180^(∘).

The sum of the measures of the interior angles of a regular n -gon is given by: |
A pentagon has 5 sides. To find the sum of the measures of the interior angles of a regular pentagon, we substitute 5 for n in this expression. ( 5-2)* 180^(∘)= 540^(∘)
