one may note that 1 CC, Cubic Centimeter, or 1 cm³, is actually equivalent to 1 mL, milliliter.
so 2 cc = 2 mL.
41º
1) Since we want to find the reference angle for a -139º angle, we need to resort to the following formula

2) Note that a -139 angle is in quadrant III, since negative angles are clockwise oriented
3) Thus the Reference Angle is 41º
Answer:
Your answer should be 3, hope this helps!
