I got the speed, its 22 knots. But I didn't get the angle.
The correct angle is a bearing of 254. I got 19.9 degrees.
to get such an angle, i used sin^-1(8sin110/22.056)=Angle

to get my speed, c2=8^2-182-2(8)(18)cos110
um...anyone got a response?
everything looks correct, again the 19.9 refers to the angle inside the triangle the new bearing will be 234 + 19.9 = 253.9 which is slighly different from answer given ? not sure why
this txtbook rounds the answers. How do I know whether to add or subtract from the current bearing on which the angle/point lies?
|dw:1333624601334:dw| use the diagram
if the current was flowing the other direction then you would have subtracted
|dw:1333635586620:dw| wait...thats not a bearing...
unless I draw my diagram wrong.
oh are bearings supposed to go clock-wise? sorry sometimes i forget navigational convention
but it still works eh
bearings start from the top and go clockwise, yeah
haha oh well but the math will still work out the same because its all relative to your starting position :)
ok. thank you very much! you helped me just in time!
welcome
