The hexagon gikmpr and fjn are regular. the dashed line segments form 30° angles.

K

Step-by-step explanation:

Angle GOK measures 240° counterclockwise from G. GO≅KO, so G will map to K when it is rotated 240° CCW around point O.

Comment on rotations with unspecified direction

Since positive angles in the coordinate plane are measured counterclockwise (from the +x axis), we presume that rotations through positive angles are rotations in the counterclockwise direction. If your textbook author has chosen a different convention, use that. (240° CW would map G to P.)

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
