Question

if a ladder 25 placed on a window 20m height ground the distance between ladder and wall​

Answer 1

Answer:25m

Step-by-step explanation:

Suppose in ∆ABC

ANGLE B =90°

BY PYTHAGORAS THEOREM,

AS THE BUILDING IS PERPENDICULAR TO ROAD/FLOOR,

BUILDING IS HEIGHT AND FLOOR IS BASE

(25)^2-(20)^2=625 - 400=225

Taking square root, distance =15m

DISTANCE BETWEEN LADDER AND WALL

IS 15m

Answer 2

Answer:

15m

Step-by-step explanation

Length of ladder = 25 m

A ladder reaches a window of a building 20 m above the ground.

AB = 20

refer the figure given below

AC = 25

We are supposed to find  the distance of the foot of the ladder from the building i.e. BC

Hence the distance of the foot of the ladder from the building is 15 m
