While on a bird-watching field trip, Angelo sees a Boreal owl at the top of a tall tree. Lying on his stomach in the grass, he measures the angle of elevation of his line of sight to the owl to be 32°. He then crawls 8.6 m closer to the tree. The angle of his line of sight is now 42°. He doesn't move any closer for fear of disturbing the owl. How close did he get to the tree? How close did he get to the owl?
