Marvin has a 27-foot ladder. Safety standards dictate that the base of a 27-foot ladder should be placed 7 feet from a vertical wall.

How far above the ground will the top of the ladder be on the wall, in feet? Round your answer to the nearest hundredth.

  • math -

    a^2 + b^2 = c^2

    a^2 + 7^2 = 27^2

    a^2 + 49 = 729

    a^2 = 680

    a = 26.08
