Question

a driveway is built on an incline so that it rises 2 meters over a distance of 20 meters. what is the degree measure of the slope of the driveway?

Answer 1

To find the slope you use the trigonometrict function tan:

`\tan \theta=(o)/(a)`

o is the opposite leg to the slope

a is the adjacent leg to the slope

`\begin{gathered} \tan \theta=(2)/(20) \\ \\ \theta=\tan ^(-1)((2)/(20)) \\ \\ \theta=5.71º \end{gathered}`THen, the slope is 5.71º
