"Woodpecker math question"

A woodpecker is perched up against a 20-foot pole, pecking away!

Eventually, it chips away enough of the wood that the pole cracks, buckles, and folds over: the top of the pole landing on the ground 12 feet from the bottom of the pole.
Undeterred, it stands on the top and continues pecking away!
How high off the ground is the woodpecker?
