Question

Each interior angle of a regular polygon is 156 degrees. How many sides does it have sides?

Answer 1

`15 " sides"`

Explanation:

with regular polygons it is best to work with the exterior angles since the sum of exterior angles is `360^o`

one exterior angle =`180-`one interior angle

`:." one ext.< "=180-156=24^o`

no of sides `=360/24=15sides`
