Question

A aeroplane is 10m reaches a window 8m above the ground . find the distance of the foot of the ladder from base of the wall . ​

Answer 1

Step-by-step explanation:

Let AC be the ladder, AB be the wall.

Then in △ABC,

AC^ 2=AB^ 2+BC^ 2

(Pythagoras theorem)

10 ^2 =8 ^2 +BC ^2

BC^2=6 ^2

BC=6 m

Hence, the foot of the ladder is 6 m from the wall.
