Assuming you are using a compass to align the sundial, it will point to the Magnetic North Pole. The Earth rotates about the True North Pole, which is not in the same location. By obtaining the magnetic variation for your locale, you can make the adjustment and have an accurate set up.
The angle of a sundial in the UK at 51.34 latitude should be approximately 51.34 degrees from horizontal, as it is typically set parallel to the Earth's axis. This allows the gnomon (the part that casts the shadow) to align with the North Pole and accurately indicate the time based on the position of the sun in the sky.
A sundial in the north pole would have a steeper and shorter gnomon compared to sundials in lower latitudes. The spacing of the hour markers in a sundial in the north pole would be same; the hour lines would be 24 hours.
Expressed in miles and in a straight line, the number you want is 3,812.
You can use trigonometry to find the angle of elevation. Let x be the distance from the tip of the shadow to the base of the pole and the height of the pole be y. Then, tan(60 degrees) = y/x. Given that the height of the pole is 12 feet, you can solve for x to find the angle of elevation.
Measured in a straight line and expressed in kilometers, the number you want is 6134.82.
28.21 feet or 28ft 3in
The sunlight hits the equator at a direct angle. Sunlight glances off the south pole at an angle, so less of it is absorbed.
a sundial is very simple to use mailny because it uses the suns rays however if it is night time the use of a sundial is no longer possible on the sundial it will have numbers on it and when the sun shines on it it will cast a particular shadow that shadow should line up with a number and then it will tell you the approximate time
The angle between the Pole Star and the horizon is equal to your latitude.
You need more info, probably an angle of elevation or something like that. It may be 14ft tall.
