Question

Which set of side lengths forms a right triangle?

Answer 1

15 , 36 , 39

Explanation:

`Lets -test-using ;\\Pythagoras -Theorem=\\a^2+b^2=c^2\\\\(A.) 2,3,13\\2^2 +3^2 = 13^2\\13 = 169\\WRONG\\\\(B.) =4,6,10\\4^2+ 6^2 =10^2\\16+ 36 = 100\\52 = 100\\WRONG\\(C.) 9,12,18\\9^2+12^2=18^2\\225 = 324\\WRONG\\\\(D.) 15 , 36 ,39\\15^2 +36^2 = 39^2\\1521=1521\\\\CORRECT`

Answer 2

15, 36, 39

Explanation:

Use the Pythagorean theorem.

a² + b² = c²

2² + 3² ≠ 13²

4² + 6² ≠ 10²

9² + 12² ≠ 18²

15² + 36² = 39²
