Expert Answer:
By Pythagoras Theorem, we get
(Distance of the foot of the ladder from the wall)2= 152 - 122
= 225 - 144
= 81
→ Distance of the foot of the ladder from the wall = 9m
By Pythagoras Theorem, we get
(Distance of the foot of the ladder from the wall)2= 152 - 122
= 225 - 144
= 81
→ Distance of the foot of the ladder from the wall = 9m
