Can someone check my diagram and this table as well ,

course velocity = 300 and the direction is due east

wind velocity = 60 with a bearing of 30

track velocity = (speed , don know ) , and at a bearing of x .

i used the cosine rule and found that AB=334 km/h and x=81.1 degree .

However , the correct answer is 80 degree . Where did i go wrong ??
