on a different​ mountain, the​ straight-line distance to the peak of Mountain A is 27.4469 miles and the​ peak's angle of elevation is θ=5.2600°. ​(a) Approximate the height​ (in feet) of Mountain A. ​(b) In the actual​ measurement, Mountain A was over 100 mi away and the curvature of Earth had to be taken into account. Would the curvature of Earth make the peak appear taller or shorter than it actually​is?

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.
