What is percentage?
10%, a comparative figure denoting one hundredth of any quantity. One percent, denoted by the symbol 1%, is equal to one hundredth of something; hence, 100 percent denotes the full thing, and 200 percent designates twice the amount specified.
Let x represent the amount of athletes that finished the race this year.
Last year, 3,570 athletes finished the Silvergrove Marathon. This year, the number of runners crossing the finish line was 20% higher. Hence:
x = 3570 + 20% of (3570)
x = 3570 + (0.2 * 3570)
x = 4284
4284 athletes finished the race.

The length of each side of the triangle varies directly with the angles of the triangle. This means that the longest side would be formed by the largest angle in the triangle and the shortest side is the side would be formed by the smallest angle in the triangle.
The smallest angle in the triangle is 43 degrees. Therefore, the shortest side of the triangle would be the side opposite 43 degrees.
Therefore, the shortest side is DE
