Imagine a clock with two pointers/arms/hands, one (indicating hours) 5 cm long, the other (indicating minutes) 12 cm long. The third side of a triangle will be the imaginary line between the tips of the two arms. At 12 hrs the distance between the tips will be 12 - 5, ie, 7 cm. This is the shortest distance possible for the length of the third side.
At 6 hrs the distance between the tips will be 12 + 5, ie, 17 cm. This is the maximum length for the third side.
As the pointers rotate, the distance between their tips, ie, the length of the third side, will vary from its shortest to its longest length, so the answer to the question is that the the third side may have any length between 7 cm and 17 cm.
An interesting detail is that at 3 hrs and again at 9 hrs, when the angle between the pointers is 90 degrees, the lengths of the triangle’s three sides are the Pythagorean triple: 5 cm, 12 cm and 13 cm.
