Find the coordinates of the image after a reflection across x=3 a (0,4), b (-6,0), c (2,-3) and d (5,2) a. a (0,4), b (0,6), c (2,-3) and d (5,2) b. a (0,4), b (12,0), c (4,-3) and d (1,2) c. a (0,4), b (-6,0), c (2,-3) and d (5,2) d. a (6,-4), b (12,0), c (2,-6) and d (5,5)

you would use (d.) the law of cosines or a^2 = b^2 + c^2 – 2bc(cos a)

, b^2 = a^2 + c^2 – 2ac(cos b), or c^2 = a^2 + b^2 - 2ab(cos c). you wouldn't use b. the law of sines as it is mostly effective when 1side and 2angles are given. a and c aren't the answer for they are the improper versions of the law of cosines. hope this is .
