The reference angle is the angle made with the x-axis. For two points to have the same reference angle, they would need to have the same absolute value of their tangents = y/x.
For the first pair of points: the first point has a tangent value of 1/sqrt(3), while the second has a tangent value of sqrt(3), so these are not identical.
For the second pair of points: the first point has a tangent value of -sqrt(3), while the second has a tangent value of -1/sqrt(3), so these are
not identical.
For the third pair of points: the first point has a tangent value of sqrt(3), while the second also has a tangent value of sqrt(3), so these have the same reference angle.
For the fourth pair of points: the first point has a tangent value of
1/sqrt(3), while the second has a tangent value of sqrt(3), so these are
not identical.
So the only correct answer is the third choice.

Answer:
Step-by-step explanation:
To solve this you take 0 as the starting number, he lost 20 points so you subtract 20 and get -20. Next add 15 points. You then get -5. Then he got another answer right so you add 35 to -5. It the same if you say 35-5. Which gives you 30. So your answer is 30
