Someone called Jake the firefighter about a cat stuck in a tree in the park. Jake has to figure out how high the cat is. So he used a trig function. Jake is looking at the cat from a 50 degree angle and is standing 7 feet away from the tree... tan(50)*7= 8.3 the cat is about 8 feet high!
Ava was going to try and help Jake when she saw a little kid stuck in a different tree at the park. Ava wanted to know how big of a latter she needed. Ava is 5 feet away from the tree and the child is 7 feet high. Ava needs to find what angle she is looking at the child from. Cos-1(5/7)= 44.4 so she is looking u at the tree at a 44 degree angle!
Jake and Ava both rescue the cat and the child safely and returned the cat to its owner and the child to it's parents. It is time for Jake and Ava to load their ladders up on their truck and go back to the station but... there is one other problem that they need trig for.
Jake and Ava needed to figure out how to put the ladder back on the truck. The angle of 35 degrees. Where the ladder lays is 7 feet long. How long is their ladder? sin35(7/x)= 12.4 feet. The ladder is about 12 feet long. Jack and Ava both got the ladder on and went back to the station.
