From the top of a 250-foot lighthouse, a plane is sighted overhead and a ship is observed directly below the plane.The angle of elevation of the plane is 22° and the angle of depression of the ship is 35°. Find a. the distance of the ship from the lighthouse; b. the plane’s height above the water. Round to the nearest foot.
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.
