Mathematics for IGCSE & O level - Pythagoras' Theorem And Trigonometry (Section 3 - No. 1)
If the bearing from point X to point Y is 135 degrees, what is the bearing from point Y to point X?
45 degrees
315 degrees
225 degrees
135 degrees
Explicació
Add or subtract 180 degrees from the initial bearing to find the opposite bearing (135 + 180 = 315, which is equivalent to 315 - 360 = 225).
