Use the Pythagorean Theorem x%5E2%2By%5E2=z%5E2
12%5E2%2By%5E2=15%5E2
144%2By%5E2=225
y%5E2=81
sqrt%28y%5E2%29=sqrt%2881%29
y=9

There is no way to tell other than to say that because of the triangle inequality. Had you qualified the triangle as a right triangle and had you identified which of , , or was the hypotenuse, or had you given the measure of one of the angles of the triangle, then someone could have given you a specific answer.
