(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

a plane moving initially at 300mi/h to the east, suddenly enters region where the wind is blowing at 100 mi/h toward the direction 30 degree's north of east. What are the new speed and direction of the plane relative to the ground.

2. Relevant equations

Magnitude= sqrt(A^2 + B^2 - 2ABcos ([STRIKE]0[/STRIKE]))

Angle= [STRIKE]0[/STRIKE] = tan^{-1}(B/A)

3. The attempt at a solution

This is suppose to be a pretty straight forward question but Im not getting it. I first tried the first equation A=300 B=100. I am not coming up with the answer.
