is in the third quadrant
To find the reference angle subtract π from it, that is
reference angle = - π =
This angle is in the 3rd Quadrant and formula for the reference angle is:
The reference angle for 7π/6 is 30°.
7 π / 6 = 210° = 180° + 30°
The reference angle is 30°.
54 kilometers per hour
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.
the answer is c.
d.) 5 pi/6<...
