A ladder, 8.2 meters long, is placed with its foot 1.8 meters from a wall. How high up the wall will the ladder reach? Give the answer to the nearest tenth of a metre.

10 POINTS FIRST CORRECT ANSWER!

-
8 meters

Just use the pythagoras theorem,

[(8.2^2) - (1.8^2)]^(1/2)
= (67.24 - 3.24)^(1/2)
=(64)^(1/2)
=8 meters
