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.
A forest ranger is walking on a path inclined at 5°to the horizontal directly toward a 100-foot-tall fire observation tower.The angle of elevation from the path to the top of the tower is 40°.How far is the ranger from the tower at this time?
