Question

Find the sum of the measures of the interior angles of a convex nonagon.

The sum of the measures of the interior angles is ?

Answer 1

7πradians

Explanation:

non in nonagon means 9

nonagon has 9 sides

convex means each angle is less than 180°

sum of interior angles convex N-sided polygon=

π(N-2) radians

π(9-2) radians=

7πradians

Answer 2

answer

7π radians

steps

non in nonagon means 9

nonagon has 9 sides

convex means each angle is less than 180°

sum of interior angles convex N -sided polygon =

π(N −2) radians

π(9 −2) radians

7π radians
