Answer: B, C, E, and F
To create a triangle, the sum of the two shorter sides should be greater than the third side.
Let's say 9 is the longest side, then the third side would be greater than
[tex]9-7=2[/tex]
If we let the third side be the longest side, then its length would be less than
[tex]9+7=16[/tex]
Therefore the values that we are looking for are values greater than 2 but are less than 16 (2 < x < 16) and from the choices, these are 10, 8, 5, and 13.
