A tree on a hillside casts a shadow c = 240 ft down the hill. If the angle of inclination of the hillside is b = 18° to the horizontal and the angle of elevation of the sun is a = 48°, find the height of the tree. (Round your answer 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.
