Question 1577Navigation General

The correct answer is A) 90°. The best fix is obtained when the angle between the two lines of position is 90°. This is because at a 90° angle, the lines of position intersect at the most acute angle, providing the most accurate and reliable position fix. The greater the angle between the lines of position, the more precisely the position can be determined. The other options are incorrect because a 30° angle (B) or a 60° angle (C) would result in a less precise fix, and a 45° angle (D) is not the optimal 90° angle.
