Question

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:

12m

Step-by-step explanation:

length of ladder = 13m

distance between ladder and building = 5m

using phythagorus theorem,

(13)² - (5)² = (height of window from ground)²

(height of window from ground)² = 169 - 25

height of window from ground = √144

= 12m
