You can put this solution on YOUR website! Two cars leave the same place at the same time. Each car travels at an average of 60kph. One travels in the direction 60 degrees north-east. The other travels in the direction 40 degrees south-east. How far apart are the two after 30 minutes?
--------------------------
2 sides of the triangle are 30 kms.
The angle between them is 100 degrees
Use the Cosine Law:
c^2 = a^2 + b^2 - 2ab*cos(100)
