An angle measuring (468n)° is in standard position. For which value of n will the terminal side fall on the x-axis?

A terminal side lies on the x-axis when the angle is a multiple of 180°. For n = 5, the angle is 468 × 5 = 2,340°, and 2,340 ÷ 180 = 13. So the angle makes 13 half-turns and ends on the x-axis; the correct choice is n = 5.
