12. 8.2 Surveying: To find the distance between two points A and B, a surveyor chooses a point C that is 420 yards from A and 540 yards from B, If angle ACB has measure 63°10', approximate the distance between A and B. You will need to supply your own sketch for this problem. Give distance AB to the nearest yard. Sketch:

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.
