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.

Answer 1

Answer:

The dock is $4.58$ $ft$ high

Step-by-step explanation:

we know that

Applying the Pythagoras theorem

Let

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

$11^2=x^2+10^2$

Solve for x

$x^2=11^2-10^2$

$x^2=121-100$

$x^2=21$

$x=\sqrt{21}$ $ft$

$x=4.58$ $ft$
