Answer:
D
Step-by-step explanation:
Under a clockwise rotation about the origin of 90°
a point (x, y ) → (y, - x ) , thus
X(- 1, - 3 ) → X'(- 3, 1 )
Y(0, 0 ) → Y'(0, 0 )
Z(1, - 3 ) → Z'(- 3, - 1 )
X X-3 Y (x,y)
3 3-3 0 (3,0)
1 1-3 -2 (1,-2)
-2 -2-3 -5 (-2, -5)
19
2(8) + 3
16 + 3
i believe it is the answer on the right because alternate interior angles add up to 180 degrees
