Question

The bottom end of a ramp at a warehouse is 10 feet from the base of the main dock and is 11 feet long.

How high is the
dock? Show your calculations

Answer 1

The dock is
`4.58`
`ft` high

Explanation:

we know that

Applying the Pythagoras theorem

Let

x------> the height of the dock

`11^2=x^2+10^2`

Solve for x

`x^2=11^2-10^2`

`x^2=121-100`

`x^2=21`

`x=√(21)`
`ft`

`x=4.58`
`ft`
