-----------------------------------
Draw the right triangle picture.
Put the sailboat at the ri. angle vertex ; the helicopter is 125ft above it.
The 24 degree angle is opposite the 125 leg
--------------------------------------------------
Find the length of the base.
tan(24) = 125/base
base = 125/tan(24) = 280.75 ft
