Question

The foot of a ladder os 6m away from a wall and its top reaches a window 8m above the ground. If the ladder is shifted in such a way that its foot is 8m away from the wall, to ehat height does its top reach? Answer me quickly please​ by draw a figure

Answer 1

Answer:

7m

Step-by-step explanation:

First, we find the length of the ladder. The ladder forms a right triangle with the ground and the wall. By pythagoras theorem,

Length of the ladder^2 = distance from the wall^2 + height of the window^2

= 6^2 + 8^2 = 36 + 64 = 100

the ladder is √100m, i.e., 10m long

now, the distance from the wall changes to 8m. So, the new height =

√(10² - 8²) = √(100-64) = √49 = 7m

Sorry, no figure....
