Question 121872
A ramp 60 m long rises a vertical distance of 8 m. Find the degree
measure of the angle of elevation to the nearest degree. 
:
You can see that this is a right triangle Let the angle = A: 
The side opposite the angle of elevation = 8 m.
The adjacent to the angle is 60m
:
That brings to mind our old friend, the "tangent" {{{side opposite/side adjacent}}}
Tan(A) = {{{8/60}}}
Tan(A) = .1333
A = 7.6 degrees ~ 8 degrees
