Answer:
Step-by-step explanation:
Because the leftmost triangle is a 45-45-90 isosceles right triangle, 
The rightmost triangle is a 30-60-90 triangle, and the side lengths are in the proportion 
from shortest to longest. Therefore, 
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.
