Answer:

It takes the moon a total of 29.5 days to complete 1 set of phase because of  the Earth's revolution around the Sun.

Explanation:

The moon is the only natural satellite of the Earth, which rotates about its axis and also revolves or orbits around the Earth. Where the Earth orbits around the Sun.

The moon completes an orbit in 27.3 days,  but due to the Earth's revolution around the Sun it would take the moon 29.5 days to return to its required point which coincides with that of the Sun. Thus completing 1 set of phase.

As the moon is rotating about its axis, it orbits about the Earth and also in synchronize motion with the revolution of the Earth about the Sun.
