Answer to Question #23915 in Geometry for Dan
Question #23915
if a ramp is 20 feet long and 28 inches high, what is the angle of the ramp?
Expert's answer
As one foot is equal to 12 inches,
20[f] = 12[i]*20 = 240[i].
The tangent of the angle of the ramp is
tg(α) = 28[i]/240[i] = 7/60.
Therefore, the angle of the ramp is
α = arctg(7/60) ≈ 6.65°.
20[f] = 12[i]*20 = 240[i].
The tangent of the angle of the ramp is
tg(α) = 28[i]/240[i] = 7/60.
Therefore, the angle of the ramp is
α = arctg(7/60) ≈ 6.65°.
