2) From a boat on the river below a dam, the angle of elevation to the top of the dam is 24°8'. If the dam is 2039 feet above the level of the river, how far is the boat from the base of the dam (to the
nearest foot)?
3) If a man is just about to ski down a steep mountain. He estimates the angle of depression from where
he is now to the flag at the bottom of the course to be 24º. He knows that he is 800 feet higher than the
base of the course. How long is the path that he will ski? (Round to the nearest foot)
4a) A man at ground level measures the angle of elevation to the top of the building to be 67º. If at this
point, he is 15 feet away from the building, what is the height of the building?
4b) The same man now stands atop a building. He measures the angle of elevation to the building
across the street to be 27° and the angle of depression (to the base of the building across the street) to
be 31°. If the two buildings are 50 feet apart, how tall is the taller building?
