Question

If an exterior angle of a regular nonagon is 40°the sum of the measure of all the other exterior angle is​

Answer 1

Answer:Answer:

the exterior Angle is 360 (sum of Angle)

Step-by-step explanation:

the sum of triangle is 180 degree

if the triangle angle is 120 so made the linear pair angle and sum of linear pair Angle is 180degree,

similarly other two angle

Answer 2

All sides are at the same length (congruent) and all interior angles are the same size (congruent). To find the measures of the angles, we know that the sum of the all anglesis 1260 degrees (from above)... and there are nine angles..so,the measures of the angle of a regular nonagon is 140 degrees.
