Question

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

12, 18, 22
8. 15. 17
10. 15.20
7.9.11

Answer 1

8, 15, 17

Explanation:

The 2nd option. You know this by using this math formula: a^2 + b^2 = c^2. That is the formula to find a right triangle. So if you square 8 and 15 you get 64 and 225, and if you add them together you get 289, which is 17^2. Hope this helps! :)
