Answer:
9>x
x must be less than 9 because the other side with a length of 14 is the hypotenuse (the longest side of a triangle). This means the unknown length must be less than 14. If x is 9 or any number greater than 9 the side length will be greater than 14 so x must be below nine so when the extra 5 is added it is still less than 14.
