antenna observes that the angle of elevation to the top of the antenna is A = 66°. He then walks s = 140 feet further away and observes that the angle of elevation to the top of the antenna is B = 44° (see the figure below). Find the height of the antenna to the nearest foot. (Hint: Find x first.)
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.
