Question

A 40 m ladder reached a window 24 m from the ground on placing it against a wall find the distance of the foot of the ladder from the wall

Answer 1

Step-by-step explanation:

So, the figure is like above

Solution :-

Let the triangle be ABC

To find: The distance of the foot of the ladder from the wall.

The distance of the foot of the ladder from the wall = BC

Let BC be x

By Pythagoras thereom,

AB² = AC²+BC²

So, 40² = 24²+x²

=> x² = 40²-24² = 1600-576 = 1024m

=> x =√1024 = 32 cm

Hence, x = BC = 32cm

Therefore, The distance of the foot of the ladder from the wall is 32cm
