You are flying a drone to get a nice picture of a lighthouse. As your drone is hovering above the ground, the angle of depression to the base of the lighthouse is 60 degrees, and the angle of elevation to the top of the lighthouse is 45 degrees. Your drone determines that it is exactly 120 feet from the base of the lighthouse. Using this information, determine the height of the lighthouse in feet

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.
