    Here is the set up:

    Use a^2 + b^2 = c^2

    Let c = length of ladder

    Let b = distance of ladder’s base from the building.

    We must find a.

    (a)^2 + (8.2)^2 = (15.5)^2

    a^2 = (15.5)^2 – (8.2)^2

    a^2 = 173.01

    Take the square root on both sides.

    sqrt{a^2} = sqrt{173.01}

    a = 13.1533265754

    We now round off to the nearest tenth of a foot.

    a = 13.2 feet
