## Claire4christ 3 years ago 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.

1. MrMoose

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

2. Claire4christ

so what triangle means

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

well aren't we fancy

9. Claire4christ

i know

10. Claire4christ

D=(28x)^2+(25y)^2

11. Claire4christ

34.54
