If you place a 13-foot ladder against the top of a 12-foot building, how many feet will the bottom of the ladder be from the bottom of the building?

5 feet

Step-by-step explanation:

When you place a 13-food ladder against the top of a 12-foot building, the ladder becomes the hypotenuse of the right angle triangle formed.

Let x be the distance of the bottom of the ladder away from the bottom of the building.

Using the Pythagoras Theorem we obtain:

This implies that:

The bottom of the ladder will be 5 feet away from the bottom of the ladder

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
