Nominally 274 degrees.
But on the real, spherical earth, the farther north you are, and the farther apart
the two points are, the more the true back-azimuth will depart from 274 degrees.

What is the back azimuth of 223 degrees?
As the request is for the back azimuth, then what is wanted is the reverse (or inverse) of the azimuth, 223 degrees. In other words, an object moved in the direction of 223 degrees (Southwest relatively), but now the desire is to reverse the travel in order to arrive at the starting point. (That starting point would have to be Northeast relatively.) One does not typically work with directions exceeding 360 degrees nor less than 0 degrees as that range is the range of a compass. Therefore, the back azimuth of 223 degrees, whatever it is, must be between zero and 360 degrees. To determine the back azimuth all that is necessary is the knowledge that 1) the back azimuth is the opposite direction of the azimuth and 2) 180 degrees either added or subtracted will yield the back azimuth, and 3) the correct back azimuth must be in the range of zero to 360 degrees. Given this knowledge and the variable definitions Ab = Back Azimuth and A = Azimuth, Ab = A + 180 or Ab = A - 180 But which equation yields the correct back azimuth? Using knowledge point #3 above, the correct result will be the one that is between zero and 360 degrees. Therefore, Ab = A - 180 = 223 - 180 = 43 degrees is the correct back azimuth. The other choice, Ab = A + 180 = 223 + 180 = 403 degrees, exceeds the range of the compass, so 403 degrees cannot be the correct back azimuth.
What is the back azimuth of 168 degrees?
348 degrees. It is the exact opposite on a compass dial. 168 is 12 degrees before due south, so the back azimuth is 12 degrees before due north.
How do you convert magnetic azimuth to grid azimuth?
To convert a magnetic azimuth to grid azimuth, subtract G-M angle.” If you have a magnetic azimuth of 270 degrees, and the G-M angle is 8 degrees, your grid azimuth will be 262 degrees.
To convert a grid azimuth to a magnetic azimuth you will need to know g-m angle. where would you look for this piece of information?

What is azimuth degrees?
An azimuth is defined as a horizontal angle measured clockwise from a north base line. This north base line could be true north, magnetic north, or grid north. The azimuth is the most common military method to express direction. When using an azimuth, the point from which the azimuth originates is the center of an imaginary circle . This circle is divided into 360 degrees or 6400 mils . NORTH IS 0/360 AZIMUTH EAST IS 90. SOUTH IS 180. WEST IS 270.
What is a back azimuth?
A BACK AZIMUTH IS A PROJECTION OF THE AZIMUTH FROM THE ORIGIN TO THE OPPOSITE SIDE OF THE AZIMUTH CIRCLE. i.e. THERE ARE 360 DEGREES IN AN AZIMUTH CIRCLE, THUS THE OPPOSITE DIRECTION IS 180 DEGREES.

To convert a magnetic azimuth to grid azimuth, subtract G-M angle.” If you have a magnetic azimuth of 270 degrees, and the G-M angle is 8 degrees, your grid azimuth will be 262 degrees.
What is the azimuth and altitude of the star Betelgeuse?
azimuth 100 degrees altitude 20 degrees
What would be the back azimuth of 265 degrees?
85 degrees (provided the distance is not more than a few miles).
What degrees is Array Azimuth specified as?
degrees
What is the formula for determining a back azimuth if the azimuth is more than 180 degrees?
If it is greater than 180, subtract 180 (270 degrees - 180 = 90 Degrees). If it is less than 180, add 180 (40 Degrees + 180 = 220 Degrees) Now the question is, what is the formula that will do this in MS Excel?
What is a back bearing in orienteering?
a back bearing is the reverse azimuth you are on. So, if you are moving on a bearing of north by northwest say at 22 degrees your back bearing is 202 degrees or the exact opposite.
What is geodetic azimuth?
Geodetic azimuth is when you measure in a Brunton compass from 0 to 360 degrees clockwise.
What are the altitude and azimuth of a star halfway between the horizon and zenith to the due east?
An object seen halfway between the horizon and the zenith has an altitude of 45 degrees.An object seen due east of the observer has an azimuth of 90 degrees.
How many degrees are there between south-east and north?
North azimuth = 0°Southeast azimuth = 135°Difference = 135°
