Question

) W, is a window against which a ladder
8.5 m long rests. The height of the
window is 7.5 m from the ground.
Without moving the bottom of the
ladder, it is turned around to rest against
a window W, on the opposite wall. If the
height of window W, is 4 m above the
ground, find the distance between the
walls.

Answer 1

Answer:

7.5+8.5+4 is the distance between the walls

Answer 2

Answer:

Step-by-step explanation:

let h=8.5

p=7.5

b= w1

then

b^2= h^2- p^2

= (8.5)^2 - ( 7.5 )^2

= 272. 25 - 56 125

= 16

then b^2 = 16

b =

$\sqrt{16}$

= 4

so , w1 = 4 m

2nd

w2 = b

h = 8.5m

p = 4 m

then b^2 = h ^2 - p^2

= (8.5)^2 - 4^2

= 72.25 - 16

= 56.25

b =  $\sqrt{56.25}$

b= 7.5

so , w2 = 7.5 m
