If each exterior angle is 9 degrees then it is a regular 40 sided polygon.
15 degrees
360/9 = 40 degrees
Interior angle+exterior angle = 180 degrees

Assuming I understand your question, the exterior angle of a regular pentagon is 72 degrees
An exterior angle of a triangle is defined to be the angle between one side of a triangle and the extension of an adjacent side. The measurement of this exterior angle is equal to the sum of the two opposite interior angles. See the related links for diagrams and sample problems.
If each exterior angle is 9 degrees then it is a regular 40 sided polygon.
The angle is 72 degrees.
Each exterior angle 36 degrees Each interior angle 144 degrees A decagon has 10 sides
15 degrees
360/9 = 40 degrees
36 degrees
360/100 = 3.6 degrees
That is not enough information.
