Answer 2

Answer:

15 m

Step-by-step explanation:

ladder ,wall, ground these will form a right angled triangle

according to Pythagorean theorem

(25)^2= (distance of the foot of the ladder from the building.)^2 + (20)^2

distance of the foot of the ladder from the building.=

√(625-400)

= √225

= 15 m

so distance of the foot of the ladder from the building.= 15 m
