You are at the top of a 40-meter-high cliff and looking down at a boat that is 100 meters away from the base of the cliff. What is the angle of depression to the boat?
Using the tangent function: tan(𝜃)=height from the object/distance to the object
tan (𝜃)=40/100
=0.4
To find the angle: 𝜃=tan−1(0.4)
≈21.80∘
