Question 1826Navigation General

The correct answer is C) 309°. To obtain the best fix, the third bearing should be perpendicular to the first two bearings. The bearing of 043° and 169° creates an angle of 126°. The third bearing should be at an angle of 90° to this, which is 309°. The other options are incorrect because they do not provide a bearing that is perpendicular to the first two. A) 073° and D) 356° are not perpendicular, while B) 192° is 180° off from the optimal solution.
