Question

a ladder 17 m long reaches a window which is 8 m above the ground on one side of a street keeping its foot at the same point , the ladder is turned to the other side of the street to reacha window 15 m high . Find the width of the street​

Answer 1

Answer:

23m

Step-by-step explanation:

In one side, the ladder forms a rectangular triangle and in the other side also.

In one side, according to the Pythagoras theorem,

17*17=8*8+x*x

so, x=15

In other side also,

17*17=15*15+y*y

so, y=8

Therefore, total width of the road is

15+8=23m.
