which of the following could be the length of the side of a right triangle

Answer 1

The last one because (1,5)^2 = (0,9)^2 + (1,2)^2

Answer 2

Answer:

The last one

Step-by-step explanation:

If you were to multiply each of the numbers by 10, you would get

9cm, 12cm, 15cm.

If you divide by 3,

3cm, 4cm, 5cm.

That is a 3-4-5 triangle, and that is a pythagoren triple.

Since we mulitplied and divided the same for all 3 numbers, it still works for the original triangle (0.9, 1.2, 1.5)
