Текст Раскадровки
- 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
