Answer:
D. (12,3)
Step-by-step explanation:
From the graphical diagram attached below ; we would realize that the x-coordinate is in the positive direction and the y-coordinate is in the negative direction.
Initially, the location of S = 12 to the horizontal x axis from the graphical diagram. So, if the trapezoid RSTU is rotated 90° clockwise about the origin to produce trapezoid R'S'T'U, we will have :
S' = 3
Thus; the (x,y) coordinate of R'S'T'U = (12,3)
