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 90 39d D side view overhead view 32. When written in scientific notation, which of the following expressions is equal to the number of blocks used to construct the pyramid? F. 2.3 x 106 G. 7.8 x 106 H. 8.3 x 106 J. 23 x 10 K. 78 x 10

Ratios
A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.
Trigonometric Ratios
Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
