Question

DO ev ew 1 A local business is installing a ramp to the back door of t the ramp is 80 inches while the vertical height of the ran What is the approximate degree measure of the angle of 2

Answer 1

Using the given information, let's make a diagram

To find x, we just have to use the sine function which is equivalent to the ratio between the opposite leg and the hypotenuse.

`\begin{gathered} \sin x=(20)/(80)=(1)/(4) \\ x=\sin ^(-1)((1)/(4)) \\ x\approx14 \end{gathered}`

Hence, the angle of elevation is 14°.
