One day, Craig wanted to climb a buliding, figured out he was20 feet away and he is at an angle of 70 degrees. He has to figure out how tall it is so he does tan(70) x 20 meaning the bulding is about 55 feet high
He thinks that building is not the right one to try this dangerous feat
He finds another and he is 30 feet away from the 42 foot building and he wants to find his angle of elevation so he does tan^-1 (42/30) and finds it is 54.5 degrees
He still simply thinks this is not the right building
The building is 53 feet high and he is at an angle of 60 degrees and he needs to find out how far he is away so he uses sin(60) x 53 which means he is 46 feet away
He decides not to climb the building cause hes scared
