    Second leg = 15

    Step-by-step explanation:

    From my understanding, you are supposed to find the second leg of the right triangle by Pythagoras theorem.

    Hypotenuse: 25

    One leg: 20

    Second leg: x

    Pythagoras theorem: hypotenuse² = adjacent² + opposite²

    c² = a² + b²

    25² = 20² + b²

    b² = 25² - 20²

    b² = 625 - 400

    b² = 225

    b = √225

    b = 15

    Therefore, the second leg of the right triangle is 15.
