Map Direction Rotation Explained
This question involves understanding how directions change when a map is rotated. We need to figure out the new direction of Northeast after a specific rotation is applied.
Understanding the Rotation
The problem states that the map is placed such that the direction 'East' now points towards 'Southeast'. Let's analyze this change:
- The standard direction 'East' corresponds to 90 degrees on a compass (assuming North is 0 degrees).
- The new direction 'Southeast' corresponds to 135 degrees on a compass.
- The difference between the new direction and the original direction is:
$135 \text{ degrees} - 90 \text{ degrees} = 45 \text{ degrees}$
- Since Southeast is clockwise from East, the map has been rotated by 45 degrees clockwise.
Applying Rotation to Northeast
Now we need to find out where 'Northeast' will point after this 45-degree clockwise rotation.
- The standard direction 'Northeast' corresponds to 45 degrees on a compass (midway between North at 0 degrees and East at 90 degrees).
- We apply the same rotation of 45 degrees clockwise to this direction.
- New angle = Original angle of Northeast + Rotation angle
New angle = $45 \text{ degrees} + 45 \text{ degrees} = 90 \text{ degrees}$
- The direction corresponding to 90 degrees on a compass is East.
Conclusion
Therefore, if the map is rotated so that East becomes Southeast, the Northeast direction will become East.
