20° Above the horizon, all the time that it's night and you can see it.
Because earth's axis points (about) at Polaris, it appears to hold still throughout the night, while all other stars spin around it. Of course, in reality the observer is spinning, while the stars's motion is insignificant even over the span of years.
The inclination is 20°, since the star would be directly above you at the north pole (90°) and right on the horizon at the equator (0°).

No, Polaris is under no circumstances overhead in case you stay on the equator. that is going to continually be close the the horizon. the in common words position the position Polaris will be overhead is on the point of the North Pole, interior of seventy six.7 km. The declination of Polaris is 89 ranges 18' 40 8" N, as of mid-year 2011. This alterations *very* slowly, and in about 12,850 years the declination will attain a optimum of about sixty six.5 ranges. So interior the year 14,850 Polaris will be overhead at your time of the day, if you're at sixty six.5 ranges N. perhaps (or maybe no longer) in some billion years, Polaris will flow adequate to be overhead at 20 N.

All who have studied.....Polaris is our pole star but it is no longer exactly over the north pole. Its elevation would be approx 20 degrees give or take a degree as it now circles the polar point in the sky. (look at circumpolar star trail pictures, Polaris forms a circle.) AND...it is there day or night whether we see it or not. But rounded off, it appears the same distance above the horizon as the latitude of the observer.

Instead, suppose you are in the north pole.
Polaris is exactly above you. It makes a right angle with horizon, 90°, there. By the way, you are standing in the 90° northern latitude.
Now, move south to the equator and as soon as you arrive, turn to face north.
Where’s Polaris? It should be in the horizon, right?
Makes 0° with horizon. Coincidentally, you are standing in 0° latitude.
Now, slowly go back towards north. Polaris begins to rise above horizon.
Stop 20° north.

The correct answer is 20 degree. Because Polaris is at the imaginary line of extension of spin axis.
