Answer:
4.9 feet
Step-by-step explanation:
First, we need to determine the height of the building using the following:
Where
H = Height of the building
L = Length of the first ladder = 20ft
B = Distance from the base of the building = 10ft
So, we have:
Next, is to determine the distance of the new ladder from the base of the building (B) using Pythagoras theorem using:
Where
--- Length of the second ladder
----- Height of the building
So, we have:
Solving for B2, we have:
