Find the bearing of x from Y if the bearing of Y from X is 180°.
If the bearing of Y from X is 180°, it means that Y is directly opposite to X. In other words, if we imagine X as the starting point and draw a straight line from X to Y, the bearing of x from Y would be in the opposite direction from Y to X, making it 0° or due north.
To find the bearing of point X from point Y, given that the bearing of Y from X is 180°, we need to add 180° to the bearing of Y from X.
So, the bearing of X from Y would be 180° + 180° = 360°.
Therefore, the bearing of X from Y is 360°.
