Distance from wall to foot of ladder AB = 6 m
And
Height of window BC = 8 m
So,
Let length of ladder AC = x m
Now we apply Pythagoras theorem in triangle ABC , As :
AC2 = AB2 + BC2
x2 = 62 + 82
x2 = 36 + 64
x2 = 100
x = 10
So,
Length of ladder AC = 10 m
Now the distance of foot of ladder from wall AB = 8 m
And
We know length of ladder AC = 10 m
So,
Height of tip of ladder BC = h
Now we apply Pythagoras theorem in ABC , As :
AC2 = AB2 + BC2
102 = 82 + h2
h2 = 100 - 64
h2 = 36
h = 6
So,
The tip reach at height of 6 m .
