Question

A ladder 45 ft tall when set against a wall of a house, just reaches the
window at a height of 27 ft. How far is the lower end of the ladder from
the base of the wall?​

Answer 1

Step-by-step explanation:

since the wall and ladder makes a right anggle triangle

using h^2=p^2+b^2

45^2=27^2+B^2

1296=B^2

b=36ft
