Answer:
Step-by-step explanation:
For any polygon the sum of the exterior angles is 360. Since The polygon is regular divide 360 by 12 to get the exterior angle measure. Interior and exterior angles are supplemental so subtract the exterior angle measure from 180.<span>

If we want to know what percent of a number A is of another
number B, then all we have to do is to simply divide number A by number B. Then
either we move the decimal place of the answer two places to the right or
multiply the answer with 100, either method results in the same number.
So the percent of tested people who had an allergic reaction
to the new lotion is:
percent people = (15 / 200) * 100
percent people = 0.075 * 100
percent people = 7.5%
Therefore 7.5% of the people had allergic reaction.
