Question

the ratio between the exterior angle and the interior angle of a regular polygon is 2:7 name the polygon(based on it's sides)​

Answer 1

Answer:

Nonagon

Step-by-step explanation:

A regular nonagon has 9 sides and so 9 exterior angles all of which are equal to 360/9 = 40 degrees.

The interior angle = 180 - 40 = 140 degrees.

Exterior : Interior = 40° : 140°

⇒ $\frac{40}{140}$

⇒$\frac{2}{7}$

⇒ 2 : 7
