A 6.5 m long ladder is placed against a wall such that its foot is at a distance of 2.5 m from the wall. Find the height of the wall where the top of the ladder touches it?



★ REQUIRED QUALITY ANSWER​

Answer 1

Answer:

In triangle ABC

by Pythagoras theorem

AC^2=AB^2+CB^2

CB^2=AC^2-AB^2

CB^2=(6.5)^2-(2.5)^2

=42.25-6.25

=36

CB=6

therefore the height of the wall is 6m.
