A basketball gymnasium is 40 metres high, 90 metres wide and 210 metres long. For a half time stunt, the cheerleaders want to run two strings, one from each of the two corners above the basket to the diagonally opposite corners of the gym floor. What is the cosine of the angle made by the strings as they cross?

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.
