A pilot spots the airport at an angle of depression of 29°. The plane is flying at an altitude (height) of 530 ft. What is the ground distance (distance along the ground) from the plane to the airport to the nearest foot? Draw a picture, set up an equation, and solve for the missing measurement.

Concept explainers

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.

Question
