this is a probability question::

The 3rd side can't be any more than to sum of the two sides. And it can't be any smaller than the difference of the two sides. That's because the two shorter sides always have to add up to more than the longest side.

CA < 17 + 4
CA> 17-4

Let's compute each of those:
17+4
= 21

17 - 4
= 13

Answer:
13 <CA < 21
your best answer is 18 because it lies between 13 and 21
