Question

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

Answer 1

As we know it forms a right angled triangle

Hypotenuse=10m

One side=8m

By pythigoras theorem

8²+x²=10²

64+x²=100

x²=36

x=6m( dist of the foot of ladder from wall)
