Question

A 15 m long ladder reached a window 12 m high
from the ground on placing it against a wall at a
distance a. Find the distance of the foot of the
lader from the wall​

Answer 1

Answer:

we have to found base by pathagorus therom so answer is 9meters

Answer 2

Answer:

It's forming a right angle triangle , because a wall is always perpendicular to ground

So , Hypotenuse =15m

Perpendicular=12m

Base=?

H^2= B^2 + P^2

15^2= B^2 + 12^2

225= B^2 + 144

B^2 = 81

B = 9

HENCE , distance of the foot if ladder from the wall is equal to 9m.

I HOPE IT'S HELPFUL !

HAVE A GREAT DAY !
