Question

a skateboard ramp at a park has an inclination of 54° and its base is 12 feet long. what is the length to the nearest foot of the ramp? the ramp is ______ feet long.

Answer 1

`\begin{gathered} \cos (54)=\frac{\text{adjacent side}}{hypotenuse} \\ \cos (54)=(12)/(x) \\ \\ x=(12)/(\cos (54)) \\ \\ x\approx20.4156 \end{gathered}`

the ramp is 20.4 feet long.​
