Answer:
6cm
Step-by-step explanation:
Let AB = Length of ladder
BC = Height above the ground
AC = Distance of foot of ladder from wall
Applying Pythagoras theorem on Situation 1,
AB² = AC² + BC²
= 6² + 8²
= 100
AB = 10
Applying Pythagoras theorem on Situation 2,
AB² = AC² + BC²
10² = 8² + BC²
100 - 64 = BC²
BC² = 36
BC = 6cm
