Question

Which set of three side lengths can be

used to make a right triangle?
39, 49, 59
39, 41, 45
39, 80, 89
39, 49, 59

Answer 1

39,80,89

Explanation:

Right triangles hypotenuse squared should equal the sum of its other side lengths. A^2+B^2=C^2. The hypotenuse is the longest length (89).

39^2+80^2=89^2

7921=7921
