Question

A 5.5 m long ladder is leaned against a wall. The ladder reaches the wall to a height
of 4.4 m. Find the distance between the wall to the foot of the ladder.

Answer 1

Answer:

Step-by-step explanation:

The distance between wall and foot of the ladder = (AB) = zm

By using Pythagoras theorem,

(BC)

=(30.35)−(19.36)

z

z=3.3 m

Hence, the distance between the wall and the foot of the ladder is 3.3m
