Solution
The correct option is A AC=6 m
Let AB be the ladder B be the window and CB be the will Than ABC is a right triangle right angled at C
∴AB2=AC2+BC2∴AB2=AC2+BC2
SO 102=AC2+82102=AC2+82
OR AC2=100−64AC2=100−64
OR AC2=36AC2=36
OR AC=6 m
So the foot of the ladder is at a distance of ^ m from the base of the wall.
