Show answer & explanation
Correct answer: B
Start: facing South-East.
Turn 180° clockwise: South-East + 180° = North-West.
Turn 360° anticlockwise: a full rotation leaves direction unchanged, so still North-West.
Turn 270° clockwise: North-West + 270° = 315° + 270° = 585° ≡ 225° (mod 360), which corresponds to South-West.
Compass-angle reference: North = 0°/360°, North-East = 45°, East = 90°, South-East = 135°, South = 180°, South-West = 225°, West = 270°, North-West = 315°.
Final direction: South-West.
