Question 237013
If a ramp starts at ground level 156 ft from the base of the platform and the angle of elevation is 20 degrees how long is the ramp?
--------------
Draw the picture.
You have a right triangle and you need to find the hypotenuse.
---
cos(20) = base/hypotenuse
hypo = base/(cos(20))
hypo = 156/cos(20)
hypo = 166.01 ft
