How many sides does a regular polygon have if each exterior angle measures 30? a 15 sides b 12 sides c 14 sides d 11 sides

In any polygon, the exterior angles will always total to 360°.

We know that it is a regular polygon and so each exterior angles equals the same as each other.

Therefo see, if we do 360÷30 we would be able to find out how many sides there are in this regular polygkn:

360/30=12

Therefore the regular polygon has 12 sides
