Question 326840
To find the measure of each exterior angle of a regular polygon, you just divide 360 degrees by the number of sides.  This can be written as:
A = 360/s  (where A = measure of exterior angle, s = number of sides)
Since we know that the measure of the angle is 30 degrees, we can plug this in for A and solve for s:
A = 360/s
30 = 360/s
30s = 360
s = 12
So the polygon has 12 sides.
