Question

How many sides does a regular polygon have if its interior angles

A. 156
B. 162

Answer 1

i) 156 degrees
The exterior angle is 180-156
=24
The number of sides=
`(360)/(24)`
The number of sides= 15 sides

ii) 162 degrees
The exterior angle= 180-162
=18
The number of sides=
`(360)/(18)`
= 20 sides
