    For this case we can model the problem as a rectangle triangle.

    We have two sides.

    We want to find the hypotenuse of the triangle.

    We have then:

    h = root ((30) ^ 2 + (16) ^ 2)

    h = 34 feet

    Answer:

    is needed a ladder of 34 feet long so that an electrician can reach the place where the light is mounted
