Question

14. A 12 m ladder reached a window of 3m high from the ground on placing
it against a wall at a distance x. Find the distance of the foot of the ladde
from the wall.​

Answer 1

Step-by-step explanation:

Given-:

Height=3m

Hypotenuse=12m

Since,Base=X

According to the Pythagoras Theorem-:

${h}^{2} = {p}^{2} + {b}^{2}$

${12}^{2} = {3}^{2} + {b}^{2}$

${b }^{2} = 144 - 9$

$b = \sqrt{135}$

b= 11.62m
