The coordinates of the endpoints of EF are E(6,-4) and F(5, -3). After a translation, the coordinates of the
endpoints of the image of EF are E' (2, -1) and F'(1, 0).
What translation was performed on EF ?
A (x, y) = (x+1, y - 1)
B (x, y) → (x+4, y-3)
C (x, y) → (x-1, y + 1)
D (x, y) → (x-4, y + 3)

answer: the answer is 127 degrees

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
