Here we can use the nifty "triangle side rule".
Recall:
For a triangle with sides a,b,c to be a valid triangle, these relations must hold:
a+b>c
b+c>a
c+a>b
Using the above, we can discover a range for X, since we know that the figure is indeed a triangle.
9+3>x
12>x
and
3+x>9
x>6
We know that x is a number between 6 and 12. We don't know what number, but that is not relevant. QB is 5.9, which is under our range - therefore QA will always be larger.

The question asks if the length of the third side of a triangle, x, is greater than or less than 5.9. The third side of a triangle is greater than the difference and less than the sum of the other two sides. The other two sides of the triangle are 9 and 3, which means that the difference is 9 − 3 = 6, and the sum is 9 + 3 = 12. So, x is greater than 6 and less than 12, which means that x is greater than 5.9. The correct answer is (A).
