23.5 degrees, the same as the "tilt" of Earth's rotational axis in space, the cause of the seasons.
The Moon's orbit is tilted about 5.145 degrees to the plane of the ecliptic, Earth's orbital plane around the Sun. (The tilt is between 18.3 degrees and 28.6 degrees to Earth's equator.) If you want an answer for your homework or whatever, the answer is about a 5 degree angle between the Moon's orbit and the Earth's orbit. -My source is; Page 27, Chapter 1, Section 2, of the Science Explorer-ASTRONOMY Text book.
About five degrees
GEOSTATIONARY=GEO+STATIONARY MEANS EARTH+FIXED POINT thus geostationary orbit is orbit around the earth is in the same plane as that defined by the earths equator at an altitude of 22,236 miles (35,786 km eg say satellite such that it appears to be stationary to the orbit of the earth above the equator all day long. where as sun synchronous orbit occurs from north to south pole as the earth rotates
I'm not sure what you mean by "a stable orbit". The Earth's center of mass ... nominally the Earth's center ... always lies in the plane of any Earth orbit, so the ground track of the orbit must either cross the equator or coincide with it.
That plane contains what is called the celestial equator, the projection into space of earth's equator. Not to be confused with the ecliptic, which is the plane containing earth's orbit around the sun.

it is because the angle between the plane of the earth,s orbit of that of the celestial equator equal to approximately 23"27 minutes at pressent
About five degrees
No. The equator is tilted about 23.5° from the plane of the Earth's orbit.
In the context of satellites, the inclination angle is the angle between the equator and the polar orbit. The polar satellite has high angle of 90 Deg and the Geo SAT has angle of 0 Deg
The tilt of the Earth's orbit (in degrees) is 23.45229 - 0.01301T where T is the time in centuries since 1900. In 2013 it is 23.43759 degrees.

Yes - actually it is caused by the varying angle between Sun, Earth, and Moon; and that depends mainly on the Moon's orbit.
I'm not sure what you mean by "a stable orbit". The Earth's center of mass ... nominally the Earth's center ... always lies in the plane of any Earth orbit, so the ground track of the orbit must either cross the equator or coincide with it.
There is an angle of about 66.5° between the plane of the earth's orbit of the sun and the earth's axis of rotation. Given a default expected angle of 90° for natural satellites in general, the deviation is about 23.5°.
That plane contains what is called the celestial equator, the projection into space of earth's equator. Not to be confused with the ecliptic, which is the plane containing earth's orbit around the sun.
23.5 degrees. That's the angle between the axis of the Earth and a line that is perpendicular to the plane of Earth's orbit around the Sun.
