Answer 2

Answer: The distance is 9.17 feet.

Explanation:

Alright, lets get started.

Please refer the diagram I have attached.

There is the ramp given of length 10 feet.

The height is 4 feet , lifted to the truck door.

It meas, the triangle formed is right triangle.

So, we can use Pythagorean theorem in this triangle.

As per Pythagorean theorem,
`c^2=a^2+b^2`

`10^2=4^2+x^2`

`100=16+x^2`

`x^2=100-16`

`x^2=84`

Taking square root on both sides

`x=9.17`

hence the distance is 9.17 feet. : Answer
