Can someone help me with this please. An airplane mechanic stands on a runway with a horizontal distance of 28 feet from the base of a control tower. The mechanic sees a pilot in the top of the control tower, 25 feet from the ground. Find the distance (to the nearest tenth of a foot) between the mechanic and pilot. Distance, to the nearest tenth = ___ ft.

    So remember the formula for distance is: \[\sqrt{(\Delta x)^2 + (\Delta y)^2}\]

    Well, as a matter of style, the 25 and 28 should probably be switched, but yes
