Question

A 10 m long ladder is placed against a
wall. The foot of the ladder is 6 m from
the wall. How far up the wall does the
top of the ladder reach?​

Answer 1

Step-by-step explanation:

Let AB be a verticle wall

and AC=10 m is a ladder.

The top of the ladder reaches to A and distance of ladder from the base of the wall BC is 6 m . Hence, the height of the point on the wall where the top of the ladder reaches is 8 cm.
