Question

4. A ladder, 17 m long, when set against a wall of a house, reaches the top of the house. If the foot of the
ladder is 8 m away from the house, find the height of the house.
​

Answer 1

Answer:

H^2 =AC^2 =17^2=289

H^2=AB^2+BC^2

289=8^2+AB^2

289=64+AB^2

289-64=AB^2

225=AB^2

AB=√225

AB=15m
