Question

in the road of our locality there is a ladder of 15m length kept in such a way that it has touched millis windows at a height of 9m above the ground now kepping the foot of the ladder at the same point of thata road the ladder is rotated in such a way that it touched our window situated on the other side of the road. if our window is 12m. above the ground, then let us determine the breath of that road in our locality.

Answer 1

Answer:

let the width of road be x

then

in triangle ABC

by pyrgagoras theorem

bc^2=ac^2-ab^2

=100-64=36

underoot of 36 =6

therefore bc =6 m

then again consider another triangle

BCD

were bc is ladder cd is base and bd is attitude

so again by pythagoras theorem

cd =8 m

then

x(width of road)= 8+6=14meters
