How many degrees is the western horizon?
180 degrees. Split into three lots of 60 degrees.
South-west.....west....north-west.
That way the real west bit is 60 degrees
Other way is, north west and south west are 90 degrees each. West is the middle half of each.
2 x 45 = 90
Or you can say...north,south,east,west, 90 degrees each. 4x 90 = 360
Same thing...90 degrees
If you're paying tax on it the first way is really the true one.
If you're marking or describing your real estate for sale the second way is the absolutely real one.
Honest.
Third way is.....as wide as my picture. That's 20 degrees.
Looking west.
-ish
But if you really want the most southerly to the most northerly points of the western horizon it goes from due south to due north via the western side.
All of it. 180 degrees.
..........
oh, and it's the azimuth by the way, not the lat/long you want for that.
Changing your lat.long just changes where you see the western horizon from.
Up and down is altitude, across or how far round is azimuth.

The point due west at 270 degrees azimuth is a point. Not a western horizon.

Asked for an angular width, solves for distance.....theory value.
Dear O dear, ladder is 2lb high.
Fah...boils down to maths. A point has no dimension. Neither does an edge. Measure from the edge of a hole or the diameter of a hole from the same point, not a bit to one side. You got that bit..the point that is neither. It's also the start of both.
North and south are not one degree wide. If they are, what are east and west? Four degrees of dead space that way. 356 left for the rest of it.
What about a compass marked in Mils? North is 1 Mil wide?
...1000 mils=1 radian....by definition.
6400 Mils=360 degrees on some compasses. Not all. Standard artillery compasses.

270 degrees is a point. One side is north, the other south. Both end at the same point.
Couldn't see the point in decimals till I got glasses..........
1 degree is 30 yards in a mile....round figures. Visible sea horizon for five foot nine person, eyes five feet four inches above the sea is 2.3 miles Trig value. 69 feet belongs nowhere for 1 degree allowance. Lose a boat in it.
Real horizon varies with weather. Wet air bends light more, see further round the Earth. Theory value is correct for a perfect sphere in a vacuum. Real world is different.
See Slieve Donard from Port Erin, rain coming....
Can't see it...raining usually. Or the air is very dry.

After all that, define west for the purpose you want it for.
Is a wide hat wider than a wide ocean? A hat held close enough can block out the whole visible ocean.

How many degrees is the western horizon?
It depends on how you define %26quot;western%26quot;. It might be 90 degrees, because 90 * 4 = 360 and there are 4 cardinal directions (North, East, South, West) in the full 360 degrees of the circle of the horizon. But if you consider southwest to be not part of west, then it is less. And if you consider west-southwest to be also different it is smaller still.
Western horizon is at270degree azimuth and zero degree altitude.
Hyman eye can see about 160degree.But all that is not west.
I think jonal is close, but I can make a valid argument for %26quot;179%26quot; degrees west, cause the corollary would be 179 degrees east. with a %26quot;point%26quot; at north and south that is neither...
1degree north
1degree south
179 east
179 west = 360degrees
It depends entirely on your altitude above the spherical earth surface:
Distance to horizon D = 鈭?2Rh + h虏) where R is the earth's radius and h is your height above sea level.
dLat = 卤 arctan(D/R)
dLong = 卤 arctan[D/(Rcos(Lat))]
