To create a triangle, the sum of the two shorter sides must be greater than the third side.
If 7 is the longer side then the missing side must be greater than 7 - 4 = 3
If the missing side is the longer side then the missing side must be less than 7 + 4 = 11
Thus any length that is greater than 3 and less than 11.
