Question

In a regular polygon,the ratio of the inner and outer angle is 7: 2 . What is each angle ? How many sides does the polygon have?​

Answer 1

Answer:

nonagon having 9 side

Step-by-step explanation:

As sum of all exterior angles is 360∘ , total number of sides must be 360∘40∘=9 and polygon is nonagon. If it is not a regular polygon, 7:2 ratio must be between sum of all interior angles and sum of all interior angles. and n=7+2=9 and polygon is a nonagon.
