Concept explainers

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.

If there is a landmark that can be seen from two locations, the distance across a river can be determined by measuring the distance between the two observers. If the first observer is directly across the river and the second observer is at a 30 degree angle from the landmark, the distance can be calculated by using a 30°30°-60°60°-90°90° right triangle. Referring to the diagram above, determine the distance across the river if the distance between observer 1 and observer 2 is 1,2631,263 meters. The distance across the river is about meters to the nearest tenth.
