Question

Is triangle abc a right triangle? AB=5, BC=7, AC=11.5

Answer 1

Answer:

No, it is not

Step-by-step explanation:

11.5 is the longest side, so it is most probably the hypotenuse

using the formula a²+ b² = c², lets input the numbers

5² + 7² = 11.5²

25 + 49 = 132.25

74  ≠ 132.25

So this is wrong
