A ramp leading into a building makes a 15 degree angle with the ground. The end of the ramp is 10 feet from the base of the building. Approximately how long is the ramp?

Respuesta :

Answer:

The length of the ramp is x = AC = 10.35 feet

Step-by-step explanation:

From the ΔABC

AC = x = length of ramp

BC = 10 feet

[tex]\theta = 15[/tex]°

[tex]\cos 15 = \frac{BC}{AC}[/tex]

[tex]\cos 15 = \frac{10}{x}[/tex]

x = 10.35 feet

Therefore the length of the ramp is x = AC = 10.35 feet
