- Bernard is stranded on an island and he decides to try and grab a banana from the top of the tree. Bernard is standing 13 feet away and looking at the tree at an angle of 71 degrees. He uses trig. to find out of tall the tree is. He figures out that tan(71) x 13 = 37.75. So the banana is about 37.8 feet high.

- Bernard finds a mini island real close that has a banana tree. He notices that the tree 9 feet tall and knows that the hypotenuse is 20 feet. He uses trig to figure out the distance from the tree to him because he is tired after getting to the island and he doesn't want to move for a minute. He figures out that sin-1 (9 / 20) = 26.7. So the distance is about 27 feet.
- The End
