    Short leg = x-6m

    Longer leg = x

    Hypotenuse = x+6m

    x² + (x-6) ² = (x+6) ²

    x² + x²-12x+36 = x²+12x+36

    2x²-12x+36 = x² + 12x+36

    2x²-12x+36-36 = x² + 12x+36-36

    2x² - 12x-12x = x²+12x-12x

    2x² - 24x-x² = x²-x²

    x² - 24x = 0

    x (x-24) = 0

    x = 24

    Short leg = 24-6m = 18

    Longer leg = 24

    Hypotenuse = 24+6m=30

    Check

    a² + b² = c²

    18² + 24² = 30²

    324 + 576 = 900

    900=900
