Question

An observer (O) is located 500 feet from a school (S). The observer notices a bird (B) flying at a 39° angle of elevation from his line of sight. How high is the bird flying over the school? You must show all work and calculations to receive full credit.

Answer 1

The bird is at a height of 405 feet above the school.

Trigonometric ratio

Trigonometric ratio is used to show the relationship between the sides and the angles of a right angled triangle.

Let h represent the height of the bird over the school. Hence, using trigonometric ratios:

tan(39) = h / 500

h = 500 * tan(39)

h = 405 feet

The bird is at a height of 405 feet above the school.
