A hot-air balloon is flying at an altitude of 2540 feet. If the angle of depression from the pilot in the balloon to a house on the ground below is 33°, how far is the house from the pilot? The house isO feet from the pilot of the balloon. (Do not round until the final answer. Then round to the nearest tenth as needed.)

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.
