There is a cat stuck in a tree. The fire fighters have an 11 foot ladder they can use to rescue the cat. The ladder leans against the tree at an angle of elevation of 65 degrees. They need to find how high the cat is in the tree. To do so they must use 11(sin 65°). They found that the height of the cat is 10 feet.
Another cat got stuck in a tree. They now have a 3 foot ladder, the angle created when the ladder leans on the tree it creates a 47° angle. In order to find how high the cat is in the tree, they must do 3(cos 47°). They concluded that the cat was 2 feet from the ground.
A house cat wondered outside his house and got himself suck up a tree. The Fire Fighters have a 13 ft ladder and its angle of elevation is θ°. In order to find how high the cat is in the tree, they must do cos (12/130. They concluded that the angle of elevation was 22.6°.
this baby cat has been stuck in a tree for so long it fell asleep. Fire Fighter put a ladder against the tree at an angle of elevation of 53°.From the Bottom of the ladder to right under the tree is 50 ft. In order to find the height of the cat in the tree, hey must do 50(tan 53°). They solved the equation and found out it was 66.4°.
All the cats were saved, and now they get to go home relax and hopefully not get stuck in trees for a while.
