Answer 1

Answer:

15m

Step-by-step explanation:

Length of ladder = 25 m

A ladder reaches a window of a building 20 m above the ground.

Refer the attached figure

AB = 20

AC = 25

We are supposed to find  the distance of the foot of the ladder from the building i.e. BC  

hypotenuse square= perpendicular square- base square

root 25^2-20^2=bc

15= BC
