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

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

the ramp is 20.4 feet long.​
