The sum of the measures of the exterior angles of a regular 9-gon, one at each vertex, is the sum of the measures of the exterior angles of a regular 6-gon, one at each vertex.

 The sum of the measures of the exterior angles of a regular 9-gon, one at each vertex, is equal to the sum of the measures of the exterior angles of a regular 6-gon, one at each vertex.

Step-by-step explanation:

We know that If we count one exterior angle at each vertex of all regular polygon, then the sum of the measures of the exterior angles of a polygon is always .

Thus, the sum of exterior angle is same for regular 9-gon and  regular 6-gon.

Therefore, the sum of the measures of the exterior angles of a regular 9-gon, one at each vertex, is equal to the sum of the measures of the exterior angles of a regular 6-gon, one at each vertex.

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
