Question

the ratio between the exterior qnd th interior angle is 2 : 7 .Find the number of sides in the polygon​

Answer 1

Answer:

9

Step-by-step explanation:

Ratio = 2:7

Let the common ratio be x

Hence,

exterior angle = 2x

interior angle = 7x

Hence,

2x + 7x = 180 degrees

x = 180/9 degrees

x = 20 degree

Thus,

Exterior angle= 2 x 20 = 40 degrees

Number of sides = 360/40 = 9
