The third side must be between 7 and 17. To see why, draw segment AB with length 12. Draw a circle with radius 5 around point B. You can connect vertex A to some point on the circle to obtain the third side.

The 3rd side has to be greater than the difference and less than the sum of the other 2 sides.
7 < s < 17
