Question

5. Kristin is swimming in the ocean and notices a coral reef below her. The angle of depression is 35° and the depth of the ocean, at that point is 250 feet. How far away is she from the reef?I need help.

Answer 1

`\begin{gathered} By\text{ Trigonometric Ratio,} \\ \sin 35^o=(250)/(x) \\ \text{cross multiply to get} \\ \text{x}\sin 35=250 \\ x=(250)/(\sin 35) \\ x=(250)/(0.5736) \\ x=435.86\text{ f}eet \end{gathered}`
