    Step-by-step explanation:

    Pythagorean theorem,

    leg ² + leg² = hypotenuse²

    leg² + 4² = 9²

    leg² + 16 = 81

    leg² = 81 - 16

    leg² = 65

    leg = √65

    leg = 8.06 units

    Because a squared + b squared = c squared, and we know that the hypotenuse is c, we can turn the equation into 9^2 - 4^2 = the other leg of the triangle. This equation is equivalent to 81 - 16 = 65. Then, you have to find the square root of 65 to get the other leg which is 8.06.
