To find a set of 3 leg lengths that will form a right-angled triangle, the square of the largest leg must be equal to the sum of the squares of the other 2 legs.

We try out all the options:

39² = 1521, 15² + 36² = 1521.

12² = 144, 8² + 4² = 80.

17² = 289, 13² + 9² = 250.

Since 39² equals 15² + 36², option A is the correct answer.

Let's add up all of the other sports except baseball (which we don't know)
1/3 + 1/8 + 5/12 Common denominator is 24 so let change them to 24ths

8/24 + 3/24 + 10/24 = 21/24 Since all the sport put together can be represented by the number 1, we will do 1 - 21/24
Instead of 1, I will use 24/24 (which means 1)

24/24 - 21/24 = 3/24 or 1/8 reduced. 1/8 of the student named baseball as their favorite sport.
