Question

find the number of sides of a polygon, if the ratio btw the exterior and interior angle of a polygon is 1:5​

Answer 1

Answer:

Let the ratio be 1x and 5x

therefore 1x+5x=180

6x=180

x=30

the formula to find no of sides of polygon is 360÷each exterior angle i.e

360÷30=12

the no of sides is 12 its a 12 sided polygon
