King Kong is hanging from the top of a vertical building. From a safe distance Sherman, standing on horizontal ground at point F, measures that Kong subtends an angle of 1.5°, and the angle of elevation to Kong’s foot is 47.3°. Assuming Kong is 60 feet tall (the distance from D to E), how tall is the building? See the figure below
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.
