Math Problem Statement
Out for a walk in Chicago, Morgan measures the angle of elevation to the distant
Willis Tower, and gets 3.6 degrees. After walking one km directly toward the building, Morgan
finds that the angle of elevation has increased to 4.2 degrees. Use this information to calculate
the height of the Willis Tower, and how far Morgan is from it now.
