Answer:6m
Step-by-step explanation: when the ladder touches the wall, it forms a triangle so we can use pythagoras theorem to find the distance between the lower end of the ladder and the base of the wall
so, pythagoras theorem = a² + b² = c² (or) side² + side² = hypotenuse²
substituting values for a² and c² =
8² + b² = 10²
64 + b² = 100
b² = 100 - 64 = 36
b = √36 = 6
therefore the distance = 6m
