The exterior angle of a dodecagon (a polygon with 12 sides) can be calculated using the formula for the exterior angle of a regular polygon, which is ( \frac{360^\circ}{n} ), where ( n ) is the number of sides. For a dodecagon, ( n = 12 ), so the exterior angle is ( \frac{360^\circ}{12} = 30^\circ ). Therefore, each exterior angle of a regular dodecagon measures 30 degrees.
Interior angle+exterior angle = 180 degrees

If each exterior angle is 9 degrees then it is a regular 40 sided polygon.
360/9 = 40 degrees
15 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
In the context of measuring an Angle of a Plane (APD), the exterior point typically refers to a point that lies outside the angle formed by the two lines or rays. This point can be used to help define or illustrate the angle's measurement by providing a reference for the angle's opening. By drawing lines from this exterior point to the endpoints of the angle, one can visually represent the angle and facilitate its measurement.
