Brian wants to build a ramp that leads to a storeroom 5 meters above the ground. He wants the ramp to be 10 meters long. What should the angle of elevation of the ramp be?
Let h be the end height of the ramp above the ground , l be the length of the ramp and the angle of elevation is θ∴tanθ=hl=510=0.5∴θ=tan−1(0.5)=26.5650(3dp)[Ans]
