Pythagorean Theorem

You have had a wonderful field trip so far! It has been a once in a lifetime opportunity! You and your class have seen monkeys, birds, frogs and even a sloth or two! At night, you can see a magnificent display of stars in the black sky. But this morning you awake to yelling and screaming to find your tour bus's tires are flat and all of your food has been stolen! How will you get back to civilization?? You are lucky enough to be parked right outside a rainforest tour station that has supplies, new tires and an enough food to feed everyone. There is one slight problem though... There are a series of 5 locks on the door to the station! You must get busy unlocking these locks so that you can leave the rainforest and get to the airport before your return flight home leaves! You need to work fast!
