Step-by-step explanation:
Answer:
15°, 165°, 195°, 345°
Step-by-step explanation:
The reference angle, 15°, is the smallest angle the terminal ray makes with the x-axis. In the first and fourth quadrants, the positive x-axis is the reference line. The angles will be ±15°, or 360°-15° = 345° if you require all angles to be positive.
In the second and third quadrants, the negative x-axis is the reference. That is 180°, so the reference angle will be added to or subtracted from 180° to give 165° or 195°.

Answer:
C
Step-by-step explanation:
-2b-3(2b-1)
-2b-6b-3
-8b-3
It will be 2/10 = .2 km /min
you can change it as 2000/600= 3.3 m/s
and also in ... 2×60/10= 12 km/hr
