    Answer:

    9 units

    Step-by-step explanation:

    Using Pythagoras’ identity on the right triangle.

    The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

    Let x be the length of the other leg, then

    x² + 12² = 15², that is

    x² + 144 = 225 ( subtract 144 from both sides )

    x² = 81 ( take the square root of both sides )

    x = \sqrt{81} = 9
