Question

7. A ladder 10m long reaches a window 8m above the ground . The distance of the foot of the

ladder from the base of the wall is ……………… m​

Answer 1

Step-by-step explanation:

BC2  = AC2 + AB2

AB2 = BC2 - AC2 

AB2 = 102 - 82 = 100 - 64

AB = 36

AB = √36 = 6 

Hence the distance of the foot of the ladder from base of the wall is 6 m.
