Question 22313: From the top of a 250-foot lighthouse, a plane is sighted overhead and a ship is observed directly below the plane. The angle of elevation of the plane is 22degrees and the angle of depression of the ship is 35degrees.
Find; A)the distance of the ship from the lighthouse
B)the plane's height above the water. Round to the nearest foot. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Draw the picture.
Distance of ship from base of lighthouse = 250'/Tan(35 degrees)
= 357.03...'
Plane's height above the water = 250'+(357.03...)(Tan(22 degrees))
= 250' + 144.25' = 394.25... ft.
