Not exactly the greatest diagram but it should be enough. After 3 hours, Andrea has traveled 540 miles on an 80 degree heading and Carlos has traveled 720 miles on a 210 degree heading. Basically, this creates 2 right triangles: 1 with a hypotenuse of 540 miles and the other with a hypotenuse of 720 miles. You might have enough information here to complete the problem.
