The problem presented involves analyzing a real-world scenario requiring the application of the Law of Cosines, a fundamental principle in trigonometry that relates the lengths of sides of a triangle to an angle between them. Augmenting this, the scenario requires the creation of an accurate diagram, complete with directional labels (north, south, east, west), known sides, and angles. This illustration serves as a vital visualization tool that assists in setting up the correct mathematical model for the problem.
The journey begins with a vehicle traveling due west for 30 miles. The next movement changes the direction toward S68°W, a bearing indicating the vehicle turns southward from west at an angle of 68°. First, a schematic diagram should be drawn with the initial position marked, pointing west for 30 miles, and then turning toward S68°W. It is essential to identify the points representing the start, turn, and final positions, as well as the angles at these points. The critical step involves labeling the interior angle between the two paths to apply the Law of Cosines.
In the diagram, a right triangle is constructed with the initial westward path as one side, and the second movement along S68°W, forming an interior angle with the initial path. The angle between the initial westward direction and the second path is 68°, but since the path is South of West, the actual interior angle at the vertex where the turn occurs is 112° (180° - 68°), a key concept in solving the problem. Accurate labeling ensures the correct application of the Law of Cosines:
c² = a² + b² - 2ab cos(C)
Where a and b are known sides (both 30 miles), and C is the included angle (112°). Substituting the known values allows calculating the distance from the starting point to the final position, which involves algebraic steps such as computing cosine of 112°, calculating products, and taking the square root of the resulting expression. This method ensures an exact measurement of the straight-line distance, fulfilling the problem's objective.
Adding the diagram to the work process clarifies the geometric relationship and demonstrates understanding of trigonometry principles. The labeled diagram not only visually supports the calculations but also aligns with the professor’s request for an annotated and well-structured visual aid. Properly representing the angles and directions in the diagram is crucial to developing a precise solution, emphasizing the importance of meticulous diagrammatic work in trigonometry problems.
