Question

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

A.)7, 9, 11

B.)10, 15, 20

C.)12, 18, 22

D.)8, 15, 17

Answer 1

D

Explanation:

`8^(2)` +
`15^(2)` =
`17^(2)`

64 + 225 = 289

289 = 289

Since
`a^(2)` +
`b^(2)` =
`c^(2)` the three side lengths represent a right triangle.
