    For this case the first thing you should realize is that you have a rectangle triangle where you have two of the three sides.

    Therefore, to solve the problem, you must find the third side using the

    Pythagorean theorem.

    We have then:

    h ^ 2 + 32 ^ 2 = 38 ^ 2

    We cleared h:

    h = root (38 ^ 2 - 32 ^ 2)

    h = 20.49390153

    round to the nearest tenth

    h = 20.5 m

    Answer:

    the height of the building is:

    h = 20.5 m
