The observation deck of the Skylon Tower in Niagra Falls is 166m above the river. Two boats are in the river with passengers looking up at the tower. -Boat A is 60 degrees south of east with an angle of elevation of 50 degrees -Boat B is 130 degrees south of east with an angle of elevation of 56 degrees Calculate the distance between the two boats. Include a diagram for full marks.

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.
