WPP #12 Unit O Concept 10: Angle of Depression and Elevation

Elevation
Yoshi is filming his music video and wants to have his shot at the beach. For one of his shots, he is going to be standing at the top of a lighthouse while the camera will be on the floor 18 feet away from the lighthouse. The angle of elevation from the camera lense to the top of the lighthouse is 34*14'. What is the height of the lighthouse?

Answer: 12.25 m

Elevation

Depression
Yoshi is now on the other side of the lighthouse. He hears his fans cheering him on from below 36.8 m away and looks straight at them and waves. What is the angle of depression if he was standing on the same leveled lighthouse? (Hint: disregard the orange-ish lines labeling 12.25 m; the lighthouse from Yoshi to the floor is 12.25)

Answer: 34.24*
Depression
