for an 8 foot ramp need to be elevated at an angle measure 10 degree to level with a step approximately how far does the ramp ne

d1i1m1o1n [39]

Answer:

7.878 ft far

Step-by-step explanation:

Given:

- A ramp is to be lifted to an angle Q = 10 degrees

- The total length of the ramp L = 8 ft

Find:

- how far does the ramp need to be away to hit the edge of the step

Solution:

- The question asks in "other words" the horizontal distance (d) from the ramp pivot on the floor to the edge of the step when it is lifted 10 degrees.

- We will use trigonometry to solve a right angle triangle: The horizontal distance is a projection of Length L on to the flat ground surface. Hence, we have:

cos(Q) = d / L

d = L*cos(Q)

- Plug in values:

d = 8*cos(10)

Answer: d = 7.878 ft
