A snowboarder rode a ski lift five miles directly to the summit of a mountain. The angle of elevation from the base of the ski lift to the peak is 31o. There is a second lift that has a base on the opposite side of the mountain but that climbs to the same point on the summit. If the length from the bottom of one ski lift to the other ski lift (straight through the mountain) is 21 miles, how long is the second ski lift? Round answer to two decimal places and include units.
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.
