Two tourists with a surveying tool want to measure the distance from their hotel to the Washington Monument and to the Lincoln Memorial. From the Washington Monument, they find that the angle from their hotel to the Lincoln Memorial is 64◦. From the Lincoln Memorial, they find that the angle from their hotel to the Washington Monument is 106◦. In the brochure, they read that the distance from the Washington Monument to the Lincoln Memorial is 1.3 kilometers. (a) Draw a picture of a triangle representing this situation. Clearly label the hotel, the Washington Monument, and the Lincoln Memorial. In addition, label all known side lengths and angles.
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.
