Question on Test: Hiker Displacement

[QUOTE="sysprog, post: 6231618, member: 617516"] Assuming the hiker is traveling over level ground on Earth, and disregarding surface curvature because the distances are small, you can draw a solvable triangle given the information in the test question. Presumably you already know that given 2 sides and their included angle you can construct the complete triangle. You're given 2 side lengths, but you're not directly given the included angle. The lengths of the sides, along with the 2 angles you're given relative to the cardinal points of the compass, which you already know are at 90° to their neighbors, are sufficient to construct the triangle. Please remember that although "facing South" always means looking in the direction of somewhere in Antarctica, it does NOT mean that a person in Chicago who is facing South is facing in a direction [I]parallel[/I] to the direction in which a person in New York who is facing South is facing. Similarly, 2 persons at 60° N latitude and different longitudes both facing North form an isosceles triangle with their distance apart as the base and the North Pole as the altitude/vertex point. You're given 2 sides, and 2 angles [I]relative to cardinal points[/I], and then you're asked to from that information calculate the distance, and the angle relative to a cardinal point, from the 2nd point to your point of origin.
