the polygon is decagon ......
non21:
firstly we will find the exterior angle .=180-150=30
and another formula to find is :- interior angle = 180(n-2)/n.......here n is no. of sides
than let the side x. 30=360/x
than let the side x. 30=360/x
how you find exterior angle is 300
u just use it .....interior angle = 180(n-2)/n .....150=( 180n-360)/n ...= 150n = 180n -360°...n = 12 .......it is shortcut
