Question 868355: A plane flew 1200 kilometers north. It then changed direction by turning 15 degrees clockwise and flew for another 850 kilometers. How far was the plane from its starting point?
Use the law of cosine Xˆ2=Yˆ2+Zˆ2-2(Y)(Z)CosX
Bˆ2=850ˆ2+1200ˆ2-2(850)(1200)(Cos15)
Bˆ2=192011.3
√X=√("192011.3" )
B=438.191

-------------------------
It turned 15 degs, that makes the interior angle 165 degs.
Use that for the angle.
o/w you did it correctly.
