Jambmaths question: 

A regular polygon has 150o as the size of each interior angle. How many sides does it have?

Jamb Maths Solution: 

Each exterior angle = 180o – 150o = 30o

Total sum of the exterior angles is 360o

${{30}^{\circ }}n={{360}^{\circ }}\text{   (}n\text{ is the number of sides of the polygon)}$

$n=\frac{{{360}^{\text{o}}}}{{{30}^{\text{o}}}}=12$

The polygon is has 12 sides
