**Serena**, Sunday, September 1, 2013 at 2:15pmSo for this you would use the Pythagorean Theorm.

The formula is a^2 + b^2 = c^2, where c is the hypotenuse of the triangle.

So if you know that the ladder reaches the height of 12m, that would be the hypotenuse in the triangle. 5m would be one of the legs in the triangle.

Therefore, calculate 5m^2 + ?^2 = 12m^2.

Think 5-12-13 Pythagorean triple
