Question

An exterior and interior angle of a regular polygon are in the ratio 2:7. Find a)Each exterior angle b)Each interior angle c)The number of sides of the polygon

Answer 1

Answer: 40,140 and no. of sides is 9

Step-by-step explanation:

Exterior:interior=2:7

we know exterior+interior=180

2x+7x=180

9x=180

x=180/9=20

Exterior angle=2x=40

interior angle=7x=140

Number of sides=360/exterior angle=360/40=9
