Problema Solution
A builder wishes to construct a ramp 26 feet long that rises to a height of 5.0 feet above level ground. Approximate the angle that the ramp should make with the horizontal. (Round your answer to one decimal place.)
Answer provided by our tutors
let A represents the angle that the ramp should make with the horizontal
sin A = 5/26
A = arcsin(5/26)
A = 12 degrees approximately
the angle that the ramp should make with the horizontal is 12 degrees approximately.
