Question

Find the sum of the measures of the interior angles of the figure.

Answer 1

Okay so to figure this out we will use the formula for finding the sum of interior angles of a regular polygon.

Si= sum on interior angles

n= number of sides

Si = 180(n - 2)

Since a heptagon has 7 sides, we just plug in 7 for "n"

Si = 180(7 - 2)

Si = 180(5)

Si = 900

Hope I helped
