An angle measuring 525 n degrees is in standard position. For which value of n will the terminal side fall on the y -axis?

For the terminal side to lie on the y-axis, the angle must be congruent to 90° or 270° modulo 360°. With n = 6, the angle is 525 × 6 = 3150°, and 3150° − 8 × 360° = 270°. So the terminal side lies on the y-axis, making “n is equal to 6” the correct choice.
