A cross-country competitor runs on a bearing of N60°W for 2 km, then due north for 3 km.
a) How far is he from the starting point?
Maybe from the information already given it is possible to find out other details?
The included angle is 150 degrees!
And then the law oof cosines with the sides (2 and 3) are all ya need!
Im so stupid!
But ya gotta admit, if he went an other way but due north it was over!
