Question

A 15m long ladder is placed against a wall in such a way that the foot of the ladder is 9m away from the wall . Up to what height does the ladder reach the wall

Answer 1

Step-by-step explanation:

by Pythagorean theory

hypotenuse =15m

base =9m

height?

height =√h^2-b^2

then =√15^2-9^2

=√225-81

=√144

=12

height of wall where ladder reach =12m

Answer 2

Answer:

height the ladder reaches the wall:

=v15^2-9 ^2 =v 225-81=v144=12m

12m. Ans
