To estimate the height of a building, two students find the angle of elevation from a point (at ground level) down the street from the building to the top of the building is 38°. From a point that is 250 feet closer to the building, the angle of elevation (at ground level) to the top of the building is 49°. If we assume that the street is level, use this information to estimate the height of the building. The height of the building is feet.

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.
