A person standing 130 feet away from the foot of a tall building must look up at an angle of 30 degrees to see the of the building. There is a radio antenna on the top of the building. The angle of elevation of the top of the radio antenna is 45 degrees Part A: What trigonometric relationships (sine, cosine, tangent) or knowledge of special right triangles would be used to determine the height of the radio antenna ? Part B: Write an equation to determine the height of the radio antenna. Part C: What is the height of the radio antenna?
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.
