Answer:
The horizontal distance between boat and the shark is 121.28 feet
Step-by-step explanation:
Given as :
The Distance of the shark swimming below sea level = AB = 28 feet
The angle of depression from a boat on water to shark = 13°
Let The horizontal distance between shark and boat = OA = x
Now, Tan angle =
or, Tan 13° =
Or, Tan 13° =
Or, 0.2308 =
Or, x =
∴ x = 121.28 feet
So The horizontal distance = x = 121.28 feet
Hence The horizontal distance between boat and the shark is 121.28 feet Answer
