If the top of a 4.50 m ladder reaches twice as far up a vertical wall as the foot of the

Free_Kalibri [48]

Answer:

4.02 meters.

Step-by-step explanation:

In the diagram, the length of the ladder is |AC|.

If the foot of the ladder is x meters from the base of the ladder

Then the distance of the ladder up the wall, AB=2x meters.

Using Pythagoras Theorem

$|AC|^2=|AB|^2+|BC|^2\\4.5^2=(2x)^2+x^2\\4.5^2=4x^2+x^2\\20.25=5x^2\\$Divide both sides by 5\\x^2=20.25\div 5\\x^2=4.05\\x=\sqrt{4.05}=2.01 feet$

Therefore, the distance of the ladder up the wall,

AB=2 X 2.01 =4.02 meters.
