Final answer:
The declination angle of the plane that includes the moon's orbital path around the Earth is approximately 5 degrees. As a result, the path of the Moon's orbit around the Earth during its 29-day period is slightly inclined.
Step-by-step explanation:
The declination angle of the plane that includes the moon's orbital path around the Earth is approximately 5 degrees. This means that the Moon's orbit is tilted relative to the equatorial plane by about 5 degrees. As a result of this declination, the path of the Moon's orbit around the Earth during its 29-day period is not parallel to the equator but slightly inclined.
