Answer:
238 feet.
Step-by-step explanation:
Refer the attached figure .
An observer is standing in a lighthouse 96 feet above the level of the water.i.e AC = 96 feet
The angle of depression of a buoy is 22° i.e. ∠ABC = 22°
Now we are required to find the horizontal distance between the observer and the buoy i.e. BC
Now, use trigonometric ratio.





Thus the horizontal distance between the observer and the buoy is 237.62≈238 feet.
Tan(theta)=opp/adj
Tan(22)=96/x
X=96/tan(22)
