A woodpecker pecked at a 17 m wooden pole until it cracked and the upper part fell with the top hitting the ground 10 m from the foot of the pole. Since the upper part had not completely broken off, the bird pecked away where the pole had cracked. How far was the bird above the ground?
13.5 M if I’m not mistaken. Because if it was 17 M im the air, then when it was cut it wasn’t 17 it would be less. So if it was cut 3.5 m from the top, it had to go between 10 and 17. Hope that works for you.
