2. ### Marcus and Cody want to hike to a destination 12 km north of their starting point.?

Use the Law of Cosines in both cases: Marcus: (notice that the given 30° is outside the triangle, the angle opposite the unknown side is 60°) sqrt (6^2 + 12^2 - 2(6)(12) cos (60°)) = 10.4 km Cody: sqrt (13^2 + 12^2 - 2(13)(12) cos (45°)) = 9.6 km
