A ladder 6.8m long is leaning against a wall, the foot of the ladder is 1.5m from the wall, find the height that the ladder reaches up the wall.

Pythagorus' Theorem: A2 + B= C2

Therefore... 1.5+ B= 6.82  

= 2.25 + B= 46.24

B= 46.24 - 2.25 = 43.99

SqR of 43.99 = 6.63m [The height the ladder reaches up the wall].
