Angle of Depression A man is flying in a hot-air balloon in a straight line at aconstant rate of 5 feet per second, while keeping it at a constant altitude. As heapproaches the parking lot of a market, he notices that the angle of depression fromhis balloon to a friend’s car in the parking lot is 35 degree. A minute and a half later, afterflying directly over this friend’s car, he looks back to see his friend getting into thecar and observes the angle of depression to be 36 degree . At that time, what is the distancebetween him and his friend? (Round to the nearest foot.)
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.
