Identify the hypotenuse, opposite side, and adjacent side relative to an acute angle in a right triangle, and determine sine, cosine, and tangent ratios using the appropriate side relationships. Select and apply a trigonometric ratio to find unknown side lengths or use inverse trigonometric functions to find acute angles, interpreting calculator results in degrees and rounding appropriately. Model and solve contextual problems involving right triangles, including height, distance, and angle situations, using trigonometry or the Pythagorean theorem and checking the reasonableness of results.
