Bill's cat Toby got stuck in a tree. In order to get the cat down from the tree, the firefighters need to know what height ladder has to be. Billy uses trig. to figure out what ladder they need to use. He finds out that 18*Tan*67=42.41. So they need a ladder that is 42.41 feet.
After the cat got down from the tree, the bird Bean flew up a telephone pole. Now the firefighters need to know what angle to put the ladder at. Bill uses trig. to help. He finds out Sin x= 15/45. So x= 19.47 degrees.
After Bean gets down from the telephone pole, Bill sees a bat on roof! He wants to know how many feet he has to walk to be directly under the bat. He finds out 56*cos*39=14.93. So he has to walk 14.93ft to be directly under the bat..
All the animals were happy after they got saved. And the fireman was really happy.
