Solve each problem.
Distance across a Canyon To determine the distance $R S$ across a deep canyon, Rhonda lays off a distance $T R=582$ yd. She then finds that $T=32^{\circ} 50^{\prime}$ and $R=102^{\circ} 20^{\prime} .$ Find $R S .$ See the figure.

Key Concepts

Triangle Angle Sum

The Triangle Angle Sum theorem states that the interior angles of any triangle always add up to 180 degrees. This concept is essential in solving problems where one of the triangle's angles is unknown and it enables the use of trigonometric laws by determining all three angles of the triangle.

Conversion of Angular Measurements

Converting angular measurements, such as converting degrees and minutes into a single unit like decimal degrees, is important for ensuring precision and consistency in calculations. This process simplifies the application of trigonometric functions and makes subsequent computations more straightforward.

Law of Sines

The Law of Sines is a fundamental principle in trigonometry that relates the ratios of the lengths of sides to the sines of their opposite angles in any triangle. This law is especially useful for solving oblique triangles (non-right triangles) when one side and two angles are known, allowing the computation of unknown sides or angles.
