Question

A 37 m long ladder is placed against a wall such that the foot of the ladder is 35 m away from the wall. Find the height up to which the ladder reaches the wall.

Answer 1

Answer:

12 m

Step-by-step explanation:

pythagoras theorem

hypotenuse = 37

so (37)²  - (35)² = height²

1369 - 1225 = height² = 144

so height = √144 = 12
