You are at the top of a roller coaster 85 feet above the ground. You ride 100 feet down the hill. What is the angle of depression (round to the nearest tenth)

Answer 1

this is

so,

`\begin{gathered} \sin x=(85)/(100) \\ \sin x=(17)/(20) \\ x=\sin ^(-1)((17)/(20)) \\ x=58.2 \end{gathered}`

answer: 58.2°
