Question 972728: A wheelchair ramp is to be built beside the steps to the campus library. Find the angle of elevation of the 23-foot ramp, to the nearest tenth of a degree, if its final height is 6 feet
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
The ramp is the hypotenuse and the elevation is the short leg of a right triangle
The sine is opposite over hypotenuse, and the angle of the ramp with the ground is the sine.
Sine=6/23
arc sin (6/23)=15.1 degrees.
