Kyle is at the end of a pier 30 feet above the ocean. His eye level is 6 feet above the pier.

He is using Binocular to watch a whale surface. If the angle of depression of the whale is
25°, how far is the whale from Kyle's binoculars?

Explanation:

Let the distance between them be y

sin20° =

=> 0.342 = [ sin20° = 0.342]

=> y = 33/ 0.342

=> y = 96.5 ft

So, the distance between them is 96.5 ft
