Question

A ramp covers 32 feet on the horizontal with a 5 foot rise.At what angle does the ramp rise?

Answer 1

`\begin{gathered} \tan \theta\text{ = }\frac{opposite}{\text{adjacent}} \\ \\ \tan \theta\text{ = }(5)/(32) \\ \tan \theta\text{ = 0.15625} \\ \theta\text{ = }\tan ^(-1)0.15625 \\ \theta\text{ = 8.88} \end{gathered}`
