→ A ladder 17 m long when set against the

wall of a house just reaches a window at a

height of 15 m from the ground. The distance

of its lower end from the wall will be-

(a) 8 m (b) 9 m (c) 15 m (d) 13 m

⇒Let Distance Between Ladder and Wall be x

Using The Pythagoras Theorem:-

$⇒(17)^2=(15)^2+x^2$

$⇒289=225+x^2$

$⇒x^2=289-225$

$⇒x=\sqrt{64}$
