SUMMARY
The discussion focuses on determining the third leg of a sailor's voyage using vector addition. The sailor sails 2 km east and then 3.4 km northeast, ultimately ending up 6.68 km directly east of the starting point. To find the third leg, participants suggest drawing a diagram with points A, B, C, and D, where B is the endpoint of the first leg, C is the endpoint of the second leg, and D represents the final position. The length and direction of the third leg can be calculated using triangle BCD.
