A) Bob at ground level measures the angle of elevation to the top of the mountain's slope to be 70 degrees, if at this point Bob is 18 feet away from the building, what is the height of the mountain?
B) Bob now stands atop. He measures the angle depression from where he is now to the ski resort to be 48 degree. He knows that he is 700 feet higher than the base of the course. How long is the path that he will descend?
