Question

* A 15-m-long ladder is placed against a wall to reach a window 12m
high. Find the distance of the foot of the ladder from the wall.​

Answer 1

Answer:

Step-by-step explanation:

in the question

its given

15m long ladder q=which is our hypotenuse

and 12m which is our height

now clearly by using the pythagores therom

H^2=A^2+B^2

which means

Hypotenuse^2=Altitude^2+Base^2

so we got the H and A

now we need to find B

so B^2=H^2-A^2

B^2=15 ^2-12^2

B^2=225-144

B^2=81

B= root of 81

which is 9

so therefore 9m is the distance of foot of the ladder from the wall
