Question

PLEASE HELP ME I REALLY NEED IT

Answer 1

B. 3, 4, 5

Explanation:

We solve this using the Pythagorean theorem: a² + b² = c²

Triangle A: 10, 12, 15

10² + 12² = 15²

100 + 144 = 225

244 ≠ 225 ❌

NOT A RIGHT TRIANGLE! ❌

Triangle B: 3, 4, 5

3² + 4² = 5²

9 + 16 = 25

25 = 25 ✅

RIGHT TRIANGLE ✅

Triangle C: 7, 8, 9

7² + 8² = 9²

49 + 64 = 81

113 ≠ 81 ❌

NOT A RIGHT TRIANGLE! ❌

Triangle D: 5, 12, 16

5² + 12² = 16²

25 + 144 = 256

169 ≠ 256 ❌

NOT A RIGHT TRIANGLE! ❌

I'm always happy to help :)
