Answer 1

Answer:

BROTHER 30m IS THE REQUIRED ANSWER U CAN GET IT BY PYTHAGORAS THEOREM.....

PLEASE MARK AS BRAINLIEST PLS.....

Answer 2

The distance of the foot of the ladder from the building is 30 m

Explanation:

Given that a ladder 50 m long reaches a window of building 40 m above the ground.

We need to determine the distance of the foot of the ladder from the building.

The distance of the foot of the ladder from the building can be determined using the Pythagorean theorem.

Let AB denote the height of the window of a building above the ground and  $A B=40$

Let AC denote the length of the ladder and $A C=50$

Let BC denote the distance of the foot of the ladder from the building and $B C=x$

Applying the Pythagorean theorem.

$A B^{2}+B C^{2}=A C^{2}$

    $40^{2}+x^{2}=50^{2}$

  $1600+x^{2}=2500$

             $x^{2}=900$

               $x=30$

Thus, the value of x is 30

Hence, the distance of the foot of the ladder from the building BC is 30m
