Exercise 2 Page 504

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^(∘).

900^(∘)

We want to find the sum of the interior angles of the given regular polygon. Recall the Polygon Angle-Sum Theorem.

Polygon Angle-Sum Theorem
The sum of the measures of the interior angles of a regular n -gon is given by: (n-2)* 180^(∘)

A heptagon has 7 sides. To find the sum of the measures of the interior angles of a heptagon, we substitute 7 for n in this expression. ( 7-2)*180^(∘)= 900^(∘)
