When you know the length of one or more sides in a right triangle and are looking for the angle measures of the triangle, you should use inverse trigonometric ratios. sin(1(x) is the measure of the angle where . Similarly, cos(1(x) is the measure of the angle where . tan(1 (x) is the measure of the angle where

Example 1: Using the values shown in the diagram below, compute numerical values of these trigonometric ratios of the angle A. First write the ratio, then the quotient: sin A = = = cos A = = = tan A = = = Solution: Example 2: Compute the size of angle A in Exercise 1 using the inverse tangent function. Assume the lengths are exact.

Writing Trigonometric Ratios. Warm-Up. A trigonometric ratio is a ratio of two sides of a right triangle. We can use trigonometric ratios to relate the angles of a triangle to the lengths of the triangle’s sides. In a right triangle, three relationships exist which relate the angles of a triangle to the measures of its sides. The word . opposite
