2. SuperNasr leaps to the top of a tall building (275 ft.) and, with his x-ray vision, sees poor little Geometry students trapped in an Algebra classroom 40 feet underground. The angle of depression (i.e., made by his line of sight parallel to the ground and his line of sight to the students) is 35°. If he were to "fly" down in a straight line along his line of sight (through air, soil, and concrete), how far would he have to fly? *Use the diagram to help. Straight path 40 ft

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.
