The top of a ladder is placed against the side of a house. The ladder is 15 feet long and the wall is 12 feet high. How far from the wall will the base of the ladder by positioned if the top ladder meets the top of the wall?

9 ft

Step-by-step explanation:

The ladder is 15 feet long

The wall is 12 feet high

Therefore the distance between the base of the wall and the ladder can be calculated by applying phythagoreans theory

c^2= a^2 + b^2

15^2 = a^2 + 12^2

225= a^2 + 144

225-144= a^2

a^2= 81

a= 9 ft
