Use these values: Let the hypotenuse be 70cm, vertical 24.5cm and 65.98cm for the horizontal.  A) With a protractor measure an angle of 20 degrees using your meter stick identically to the laboratory set up previously described. What are the lengths of the horizontal leg and vertical leg of the right triangle formed? Measure these values with another meter stick. B) Calculate the horizontal leg and vertical leg of the right triangle formed in problem (A) using the following cosθ = adjacent/hypotenuse and sinθ = opposite/hypotenuse C) Calculate the percent error between the calculated and recorded sides. You should obtain a small percentage

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.
