**Question:**

Each interrior anfle of a regular polgon is 144.the number of sides of the polygon is

if we divide the above value by n then we get the each interior angle...n puts its value 144

finally we get n=__10__

Formula to find out the no: of sides of polygon when interior angle is given

n = [ 360/ (180 -A) ]

n -> no: of sides.

A -> given interior angle.

n = [ 360 / (180 - 144) ]

= 360 / 36

= 10 .

(formula source : Google).

Good question Deepika.

I haven't seen this type of qstn.
