Which set of numbers could represent the lengths of the sides of a right triangle?

7, 24, 25

9, 12, 16

6,9,11

10, 15, 20

in this problem what you are really looking for is which of these sets is a pathagorean triple. That means it will solve the pathagorean theorem. (a sqaured + b squared = c squared) c is always going to be the largest number or the hypotenuse. if you plug all the number sets into the theorem, only one works and that is 7, 24, 25 which is your answer.
