Answer:

b. 36°

Simple explanation:

The measurement of the sum of the interior angle of a regular  polygon is 1440° . Now your interior angle and exterior angle with the line extended add to equal to 180 degrees since the line drawn is a straight line. Therefore, if the interior angle of the regular polygon is 1440° , then the exterior angle is 36°.

*Don't include the 0 of 1440°, 144

180 - 144 = 36°
