The sum of the angles of any polygon is 360 degrees. A regular polygon is equiangular, all the angles are the same. So dividing 360 by 9 gives 40 degrees as the size of the interior angle. To get the exterior angle, simply subtract that angle from 360, so the exterior angle is 360-40 = 320 degrees.
if exterior angle measures 5 degrees, then the corresponding interior angle would be 275 degrees {360-(5+180)}. it's impossible for a polygon to have an exterior angle of 5 degrees

Verified answer
Use the formula for exterior angles
angle = 360/n
where n = no of sides
angle = 360/9
angle = 40 degrees
therefore each exterior angle is 40 degrees

each exterior angle of a regular nine-sided figure = 360/9 deg = 40 deg.
