<span>The reference angle is closest to the x-axis.
I will assume the above is 7pi/6. That would be a reference angle of pi/6, and the sin in the 3rd quadrant is negative, so the sin theta = - 0.5</span>

Answer:
Yes, the transformation is a 270° clockwise rotation
Step-by-step explanation:
(-3, 4) ,( -4, 7) and (-2,7) transformed to (-4, - 3), (-7, -4) and (-7, -2).
Rule for 270° clockwise rotation:
(x, y) --> (- y, x)
A transformation that doesn't change the size or shape of an object.
So answer is:
Yes, the transformation is a 270° clockwise rotation
