Question

1.) Which set of numbers could be the lengths of the sides of a right triangle?a.) 8, 15, 12b.) 4,5,7c.) 12,9, 15d.) 6,6,9

Answer 1

We will determine th set as follows:

a)

`15\\e\sqrt[]{8^2+12^2}`

So, set a is not.

b)

`7\\e\sqrt[]{4^2+5^2}`

c)

`15=\sqrt[]{12^2+9^2}`

So, set c has the lengths of a rigth triangle.
