Question

ramp is 9.4m long and joins two levels, one 3.1m higher than the other find angle that ramp makes with the lower level

Answer 1

The angle ramp make with the lower level is 19.25∘

Explanation:

Using the sine function:

sin θ = H e i g h t D i f ere n c e / R a mp Length

sin θ = 3.1 / 9.4

Taking sine inverse on both sides:

θ = s i n − 1 3.1 / 9.4

θ ≈ 19.25 ∘

I hope it helped

have a great day :))
