Question

6. The foot of a ladder is 6 m away from a wall and its top reaches a window 8 m above
the ground. If the ladder is shifted in such a way that its foot is 8 m away from the wall.
to what height does its top reach?​

Answer 1

Hey there ,

Now we know that if ladder's foot is 6 m away and touches wall 8m above the ground then total length of ladder will be equal to 10 m ....

Since length of ladder remains same therefore ,,

Now , if foot is 8 m away from wall , and we know length of ladder is 10 metre..

So by Pythogaras theorem,

Height of top = 6 m
