hi buddy ! i was doing this question few days ago (7th grade).....well the ans is:
the ladder , wall with window and ground forms a right angled triangle.
its one side and hypotenuse is given we have to find another
hypotenuse= (side1)^2+(side2)^2 , (by PYTHAGORAS THEOREM)
but we have to find a side so, here starts main steps:-
(10^2) - (8^2) = x^2
100 + 64 = x^2
164 = x^2
root of 164 = 12.806= x
hence the distance between ladder and the window is of 12.806
(it is imperfect root so there is more no. ahead but that is inconsiderable)
