The builder of a parking garage wants to build a ramp at an angle of 16 degrees covers a horizontal span of 55 feet. How long will the actual ramp be? Round yoursolution to four decimal places.

Respuesta :

Let's draw the ramp to better understand the problem:

For us to be able to determine how long the ramp will be, we will be using the Cosine Function.

We get,

[tex]\text{ Cosine }\Theta\text{ = }\frac{\text{ b}}{\text{c}}[/tex][tex]Cosine(16^{\circ})\text{ = }\frac{55}{x}[/tex][tex]x\text{ = }\frac{55}{Cosine(16^{\circ})\text{ }}[/tex][tex]\text{ x = }\frac{55}{0.9612616959}[/tex][tex]x=57.216468974668940618504468175387[/tex][tex]\text{ x }\approx\text{ 57.2165 feet}[/tex]

Therefore, the answer is 57.2165 feet.
