    3 square roots of 19

    Step-by-step explanation:

    a squared + b squared = c squared

    5 squared + b squared = 14 squared

    25 + b squared = 196 squared

    b squared = 171

    b = square root of 171

    b = 3 square roots of 19

    hi

    If your wall is straight, then. you have a rectangular traingle.

    As Pythagoras tells us : wall² = ladder² - ground distance²

    wall² = 14² - 5²

    wall² = 196 - 25

    wall² = √171≈13,07
