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.
In the figure below, the distance from A to D is y, the distance from D to C is x, and the distance from C to B is h. Use the figure to solve the following problem.
If A = 41°, ∠BDC = 59°, AB = 17 and DB = 13, find x, then y. (Round each answer to one decimal place.)
