Scene #5 Acropolis -- Athens, Greece A security guard noticed this morning that one of the great marble columns was stolen in the middle of the night. Investigators believe Tanlines plans to use it as a tower for the World Conquering Device. Something I learned on my little theft vacation is the Greeks love hang gliding. I thought I'd give it a whirl with a puzzle. A Hang Glider cruises above the Parthenon at a constant altitude at 12 M/S. She looks down to the top of the Parthenon with an angle of depression of $15^\circ$. One minute later, she looks down at an angle of $52^\circ$. If the Parthenon is 13.72 m tall and the building sits 150 m above sea level. Approximately, how many meters above sea level is the glider? 408 m 512 m 665 m e = 408 h = 512 s = 665
