Question

A ladder 13 m long when set against the wall of house just reaches a window at a height of 12m from the ground. How far is the lower end of the ladder from the base of the wall?​

Answer 1

Answer:

The answer is

$\frac{60}{13}$

Answer 2

Answer:

5 m

Step-by-step explanation:

when we assume the figure formed as a right angled triangle

length of the ladder- 13 m (hypotenuse)

height of the wall- 12 m

base- x

     according to the pythagoras' theorem,

x square + 12 square = 13 square

x square + 144= 169

x square= 169-144

x square = 25

x = 5
