Question

the measurement of each interior angle of a regular polygon is 40 how many sides does it have​

Answer 1

Answer:

Measure of each interior angle=40 degree

sides of the polygon=n

(2n-4/n)*90=40

2n-4/n=40/90

2n-4=4n/9

2n- 4/n9=4

Making the denominator equal

2n*9-4n/9=4

(18n-4n)/9=4

14n/9=4

n= 4*9/14

n=18/7
