the ground speed?

I found Rx and Ry which are 543.23 and 572.22 respectively. To find the angle I took tan^-1 of 572.22/543.23 and got 46. 489 for the angle, but the answer is wrong. R=789 and I got that right so I don't understand why the angle is incorrect.

Vp + 28 = 770*cos42 + i770*sin42

Vp + 28 = 572.2 + 515.2i

Vp = 544.2 + 515.2i = 749mi/h[43.6o] CCW

= 749mi/h[46.4o] E of N.
