Answer:

140°

Explanation:

a regular polygon is equiangular, equal angles.

a nonagon is a 9 sided polygon

the sum of the interior angles of a polygon is

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

here n = 9 , then

sum = 180° (9 - 2) = 180° × 7 = 1260° , then

each angle = 1260° ÷ 9 = 140°
