A: A A Use the following information to answer questions 32-34. When it was constructed 4,500 years ago, the Great Pyramid in Egypt had a height of 147 meters and contained roughly 2.3 million stone blocks. It is estimated that 5.5 million tons of limestone, 8,000 tons of granite, and 500,000 tons of mortar were used in its construction. In the side view shown below, an ancient observer found the angle of elevation at D to the top of the pyramid to be 39°. The diagonals of the pyramid's square base, shown below, intersect at C. 147 D 90 C 390 side view overhead view
