Question

A ship is 350 feet from lighthouse which is 40 feet tall, find the angle of depression from the top of the lighthouse to the ship.

Answer 1

6.52 degrees is the correct answer

Answer 2

6.519801752°

Explanation:

Let θ represent the angle of depression

tanθ=40/350

θ=tan^-1(40/350) *tan^-1 means inverse tan*

θ=6.519801752°
