Given :
Hight of the van from the ground, h = 3 feet.
The ramp into the van makes a 12° angle with the ground.
To Find :
How long is the ramp.
Solution :
Let, length of ramp is l .
So, height of ramp in terms of length is given by :
[tex]h = l \times sin\ 12^o\\\\l = \dfrac{h}{sin \ 12^o}\\\\l = \dfrac{3}{sin \ 12^o}\\\\l = 14.429 \ feet[/tex]
Hence, this is the required solution.
The ramp should be 14.429 feet.
Given that,
- He floor of a moving van is 3 feet off of the ground.
- The ramp into the van makes a 12° angle with the ground.
Based on the above information, the calculation is as follows:
[tex]h = l\times sin 12^{\circ}\\\\l = h \div sin 12^{\circ}\\\\= 3\div sin 12^{\circ}[/tex]
= 14.429 feet
