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.

=_________ft
Given the angle of depression to a ship in the ocean is 27degrees.
Height of the light house=300ft
A Triangle is formed by the light house, ground and ship. The angle of depression is not in the triangle, but it is equal to angle of elevation of ship(alternate angles are equal).
Let AB be the tower, C be the ship
Then BC is to be found
