Answer to Question #164648 in Trigonometry for Brian Kim

Question

The entrance to a health clinic is x feet above street level. A ramp is installed from street level to the entrance of the health clinic which has an angle of inclination of 5 ◦ . The ramp is 10 feet long. What is x?

Answer 1

This will be a right triangle where b=10 and angle A is 5 degrees we want to find C

Cos A= Adjacent/hypotenuse

Cos 5 =10/C

C Cos 5= 10

C =10/Cos 5

C= 10.038198

~10.0382 that will be equivalent to x in the given question
