Question

A 25m long ladder reached a window 7m high from the ground on placing it against a wall at a distance ‘’ meter from a wall. Find the distance of the foot of the ladder from the wall​

Answer 1

Answer:

hypotenuse = 25m

height = 7m

base according to pythagoras theorem:

25^2 - 7^2 = base^2

625 - 49 = base^2

576 = base^2

base = √576

base = 24m
