lf the bearing of A from B is 215°,find the bearing of B from A
ever heard of doing a 180?
To face the opposite direction, just subtract 180°
Correct
The 215° is in the third quadrant so you will subtract the 215 from the 270. Which will be 270-215=55°.
You will subtract it from 270 because the 1st quadrant is 90, 2nd 180, 3rd 270 and the 4th 360.
If the bearing of y from x is 215°. Find the bearing x from y
To find the bearing of B from A, you need to subtract the given bearing of A from B (215°) from 180°. This is because bearings are measured clockwise from the north direction, so the bearing from A to B and the bearing from B to A will be 180° apart.
So, to find the bearing of B from A:
180° - 215° = -35°
Therefore, the bearing of B from A is -35°. Note that the negative sign indicates that the bearing is in the opposite direction from the usual convention of measuring clockwise from the north.
BB=B-270⁰
BB=215⁰-270⁰
BB =055⁰
