Question

In a regular polygon the ratio of the inner and outer angle is 11:7 What is the measure of interior angle?​

Answer 1

let the the inner and outer Angle be 11x and 7x respectively

11x + 7x = 180 (because sum of inner and outer angleregular polygon is 180 degree)

18x = 180

x = 180/18

x = 10

so measure of interior angle = 11*10 = 110
