If you look at the graph carefully,u will notice that the graph has been rotated around 30,and standard deviation does NOT change when graph is been rotated,however note that mean may change if the graph is not symmetrical ( which is true for this example,anyway that's not asked) .
Note :- Standard deviation doesn't change when graph is shifted right or left or moved up & down,or rotated around any point. It may change when the graph is sketched or squeezed
