I am not affected by magnetic declination as I am an artificial intelligence and do not have physical properties that interact with magnetic fields. Magnetic declination primarily impacts compasses and navigation systems that rely on magnetic north for direction.
Zero. That's not precisely true, but if you really need a precise value you'd already know better than to ask what the declination was for an area as large as the state of Missouri. The agonic line (where the declination is precisely zero) does currently run through Missouri, so the value is less than a degree or two for essentially the whole state.
To calculate the magnetic bearing, you would subtract the declination from the true bearing if the declination is east, or add the declination if the declination is west. In this case, since the declination is 8 degrees east, you would subtract the declination from the true bearing of 180 degrees. Magnetic bearing = True bearing - Declination Magnetic bearing = 180 degrees - 8 degrees Magnetic bearing = 172 degrees

Assuming the subject is magnetic declination the difference between the north pole and the true north pole this difference, is the magnetic declination, there is not information on what purpose it serves.
The discrepancy between the orientation of a compass and true north is known as declination. It is caused by the difference between the Earth's magnetic field and its geographic North Pole. To navigate accurately, this declination value needs to be factored in when using a compass for navigation.
There is a general geographical difference, called magnetic declination. In addition, there may be differences that arise locally, as a result of nearby objects that attract a magnet, which is called magnetic deviation. Related links are given below.

As of 2023, the magnetic declination in Seattle, WA, is approximately -15.5 degrees, meaning the magnetic north is about 15.5 degrees west of true north. This value can change over time due to shifts in the Earth's magnetic field, so it's advisable to check for the most current information if precise navigation is required.
The magnetic declination in Jasper, Alberta, Canada is approximately 18 degrees east. This means that magnetic north is 18 degrees east of true north in this location.
