A man in a balloon observes two points, A and B, on the horizontal plane. The angle of depression is thirteen degrees and ten degrees for A and B, respectively. The horizontal angle subtended by AB at a point below the balloon is forty – four degrees. If the balloon is eighty feet high, find AB. Solve and sketch the problem.

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.
