Which of the following statements is true about finding the area of a triangle given that​ A, B, and C are the measures of the​ angles, a,​ b, and c are the lengths of the sides opposite the corresponding​ angles, and h is the length of an​ altitude? Choose the correct answer.     A. In order to use the formula Area=12ab sin C, the length of two sides and the measure of the included angle must be given or able to be determined from the given information.   B. In order to use the formula Area=12bh, the triangle must be a right triangle.   C. In order to find the area of any​ triangle, the measure of at least one angle must be given.   D. In order to find the area of any​ triangle, the altitude must be given.

A:

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.
