Answer:
A point (a, b) rotated around a point (x, y) 180 degrees will transform to point (-(a - x) + x, -(b - y) + y). A point (a, b) rotated around the origin 270 degrees will transform to point (b - y + x, -(a - x) + y).
Step-by-step explanation:
5 units
x=9
90(the angle)-30=60
60-15=45
45/5=9
<u>(5(9)+15)+30=90</u>
