Both statement one and statement two are insufficient for obvious reasons. Since it doesn't mention angles you can either have a right triangle where the last side is 4 or an isosceles with the last side being 3. So insufficient.

Also the sum of two sides has to be greater than the 3rd thats the only rule that I'm aware of, plus it didn't say that the last side had to be an integer so X+3>5 or 8>X so anything from 2.000001 to 7.9999 satisfies this equation.
