The path of a satellite orbiting the earth causes it to pass directly over two tracking stations A and B, which are 75 km apart. When the satellite is on one side of the two stations, the angles of elevation at A and B are measured to be 86.8* and 84°, respectively,

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.
