The bearing point from x to y is 250°. What is the bearing point from y to x?
The bearing, not the bearing "point".
add or subtract 180. Here subtract because your initial bearing was greater than 180
250 - 180 = ?
I guess it's fine
The bearing from x to y is 250°. To find the bearing from y to x, we need to subtract or add 180°. Since 250° is greater than 180° and less than 360°, we need to subtract 180°.
250° - 180° = 70°
Therefore, the bearing from y to x is 70°.
