Jessica the firefighter was walking through the park one day when she suddenly heard a cat "meow". She looked up and saw a little kitty stuck in a tree. Jessica needed to figure out how high up the cat was. She was standing at a 76 degree angle, 15 feet away from the tree. sin76 • 15 = 8.5 The cat was nearly 9 feet up!
Adam was on his way to go help Jessica but he saw another cat stuck in a tree! Adam was 5 feet away from the tree and the cat was 8 feet high. He needed to find the angle that he was looking up at the cat at. cos-1(5/8)=51.3 So Adam is looking up at the tree at a 51 degree angle.
Jessica and Adam rescued both of the cats and were ready to return to the station except they still had to figure out how to get the ladder bac on the truck.
The angle of the ladder was at 43 degrees. The place the ladder lays is 12 feet long on top of the firetruck. How long is the the ladder? tan(43) • 12 = 11.2 So their ladder is 11 feet long.
Once Jessica and Adam got their ladder back on the truck, they headed back to the station and were proud of the work they had done today! The End!
