**Steve**, Wednesday, November 2, 2011 at 12:51pmSet 'em up and knock 'em down:

use the law of cosines to find the resultant r:

r^2 = 675^2 + 828^2 - 2(675)(828)cos(180-52.3)

Having r now, you can use the law of sines to get the resultant angle a:

r/sin(180-52.3) = 828/sin a

where a is measured in degrees east of north.
