Answer:

24.5 Ft

Step-by-step explanation:

The 25 foot ladder is leaning against a building is the hypothenuse of right angled triangle whose another side is 5 feet

Let the another side be X

Then Side^2=5^2=+another side^2=X^2=hypothenuse^2=25^2

25+X^2=625

X^2=625–25=600

X=root 600=24.49 or 24.5
