Strange, I thought you'd already posted this question previously, and that I'd already responded.

Answer 3

Never responded..

Answer 4

I got a notification saying you replied but nothing showed up :/

Answer 5

But could you please help?

Answer 6

Try using the Pyth. Theorem with each set of side lengths. If it turns out that the given side lengths satisfy the Thm., then the triangle in question is a right triangle, and so you can eliminate it.

I promised earlier to help another student, so will have to keep that promise. I'll be around, however.
