The zenith at the North Pole directly corresponds to the celestial pole, which is at a declination of +90°. The angular distance from any point on the celestial sphere is the difference in their declinations. Therefore, the angular distance from +90° (North Pole zenith) to +30° (star's declination) is 60°.
