An airplane is flying at an altitude of 30,000 feet. The distant d in feet from an observer on the ground to the plane is function of the angle of elevation 0. Defined as the acute angle between the ground and the line between the observer and the plane as shown in figure. Part A . which equation gives d as a function of 0? Part B: within the context of the situation describe what is the domain of the function d? . enter appropriate value ,bin degree. In equality below. Part C. When the angle of elevation is 75 degrees what is the distance between the observer and the plan 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.
