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
