a ladder 6 meters long leans against a wall. It rests on the ground 1 meter away from the wall. How high on the wall does the ladder rest?

a^2 + b^2 = c^2
a^2 + 1^2 = 6^2
a^2 + 1 = 36
a^2 = 35
a = 5.92 meters

A famous Greek once proved this:
On a right triangle, the square of the hypotenuse is equal to the sum of the squares of the legs.
C^2=a^2+b^2
here, c is 6
a is 1
solve for b.
