Question

find the number of sides of a regular polygon with each interior angle equal to 160 degrees?

Answer 1

exterior angle = 180 - 160 = 20

No of sides = 360 / 20 = 18

Answer 2

by interior angle u mean the angle made at the centre ?

Answer 3

inside the polygon

Answer 4

interior angles are: 360 - exterior

Answer 5

160/2 = 80

80+80+central angle = 180

central angle = 20

360/#sides = 20

360/20 = #sides = 18 ...yep
