Answer:
length of the ladder should be 16 feet.
Step-by-step explanation:
In the figure attached,
B is the window at 12 feet from the ground.
Building AB is 2 feet away from the fence DE.
Ladder AC is placed 8 feet away from the fence at a point C.
We apply Pythagoras theorem to calculate the length of the ladder.
AC² = AB² + BC²
AC = [tex]\sqrt{(12)^{2}+(2+8)^{2}}[/tex]
= [tex]\sqrt{144+100}[/tex]
= [tex]\sqrt{244}[/tex]
= 15.62
≈ 16 feet
Therefore, length of the ladder should be 16 feet.
