Question

A ladder is placed against a wall such that its foot at a distance of 3 m from the foot of the wall and its top reaches a window 4 m above the ground.Find the length of the ladder(would be great if you share me how its done)

Answer 1

Answer:

5 m

Step-by-step explanation:

with AB = 4m and BC = 5m

in this triangle we will apply Pythagoras theorem

we know that

hypotenuse2 = base2 + height2

let hypotenuse be x

base is BC

height is AB

thus

x2 = 4x4+5x5

x = √25

x=5

Answer 2

This is the answer. I think this answer will help you.
