Hi! My name is Phil, a fire fighter! I am going to help poor innocent creatures and things!
Oh no! the cat needs help! well, the wire pole is 15 feet tall, and from my feet the angle of elevation to the cat is 24 degrees. So, How do I find the correct sized ladder? I can do sin(24)= 15/x, which makes the size of the ladder be 36.9 feet!
Hurray! the cat is saved!
Oh no! a house is burning! let me call the fire trucks!
I need to find the angle of elevation I need to put the hose in! since the house is 25 ft and the distance from the house to the fire truck is 15 ft, I can do tan^-1 = 25/15, which comes to an angle of 59 degrees!
Yay! the house is saved!
