Answer:
30 unit angles
Explanation:
A unit angle is defined as an angle that measures 1 degree. To find the number of unit angles that the smaller angle 30° of a small pattern block goes through, we can divide the measure of the angle by the measure of a unit angle.
30° ÷ 1° = 30 unit angles
So, the smaller angle 30° of a small pattern block goes through 30 unit angles.
