if interior angle is 160
then by linear pair angle exterior angle = 180-160=20
sum of exterior angle = 360
then no. of sides = 360/20
=18
no. of sides for 135
180-135 = 45
no. of sides = 360/45
=8
no. of sides for 150 degree
180-150 = 30
no of sides = 360/30
=12
then by linear pair angle exterior angle = 180-160=20
sum of exterior angle = 360
then no. of sides = 360/20
=18
no. of sides for 135
180-135 = 45
no. of sides = 360/45
=8
no. of sides for 150 degree
180-150 = 30
no of sides = 360/30
