Question

b) A firefighter's ladder of length 13m was kept at a distance of 5m from a
building to reach a window on the building. At what height is the window
from the ground?​

Answer 1

Answer:

12 m

Step-by-step explanation:

hypotenuse = 13 m

distance of ladder from building = 5 m

Hence 13^2 = 5^2 + height of building ^2

height of building ^2 = 169 - 25=144

Hence height of building = 12 m
