Answer
Correct Answer: South - East
Explanation
Introduction / Context:We must find the bearing of the final point relative to the origin after a sequence of axis moves. Only the quadrant is asked (not the exact angle).
Given Data / Assumptions:
- East 30 m → (30, 0).
- Right from East is South → 40 m → (30, −40).
- Left from South is East → 30 m → (60, −40).
Concept / Approach:Positive x means East of start; negative y means South of start. Combine signs to get the quadrant.
Step-by-Step Solution:Final coordinates: (60, −40).x > 0 → East; y < 0 → South.Therefore quadrant = South-East.
Verification / Alternative check:A quick sketch shows the point down and to the right of the origin, confirming South-East.
Why Other Options Are Wrong:North-East requires y > 0; pure East requires y = 0; South is x = 0 and y < 0.
Common Pitfalls:Mixing up left/right turns relative to current heading.
Final Answer:South - East
