Question

a ladder 25m long reaches a window of a building 24m above the ground. determine the distance of the foot of the ladder from the building​

Answer 1

distance from foot of ladder to building = √25²-24²=√(25+24)(25-24)= √ 49 = 7m

Answer 2

Answer:

Step-by-step explanation:

as the ladder makes 90 degree with the building

25^2=24^2+x^2

625=576+x^2

49=x^2

x=7

therefore the distance between the foot of the ladder and the building is 7 m
