Best ResponseYou've already chosen the best response.0I got the speed, its 22 knots. But I didn't get the angle.

Best ResponseYou've already chosen the best response.0The correct angle is a bearing of 254. I got 19.9 degrees.

Best ResponseYou've already chosen the best response.0to get such an angle, i used sin^1(8sin110/22.056)=Angle

Best ResponseYou've already chosen the best response.1everything 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

Best ResponseYou've already chosen the best response.0this txtbook rounds the answers. How do I know whether to add or subtract from the current bearing on which the angle/point lies?

Best ResponseYou've already chosen the best response.1if the current was flowing the other direction then you would have subtracted

Best ResponseYou've already chosen the best response.1oh are bearings supposed to go clockwise? sorry sometimes i forget navigational convention

Best ResponseYou've already chosen the best response.0bearings start from the top and go clockwise, yeah

Best ResponseYou've already chosen the best response.1haha oh well but the math will still work out the same because its all relative to your starting position :)
