**Reiny**, Tuesday, April 10, 2012 at 6:00pmI see two vectors forming an angle of 75°

Draw the usual parallelogram with the resultant as the diagonal of that parallelogram.

R^2 = 900^2 + 2000^2 - 2(900)(2000)cos 105°

R = 2396

that's your magnitude

Now use the sine law to find the direction angle.
