If x = 10, which lines are parallel? Check all that apply. Lines b, c, d, e are cut by transversal a. Clockwise from top left, the angles formed by lines b and a are blank, (7 x minus 5) degrees, blank, blank; by lines c and a are blank, blank, (10 x + 15 degrees), blank; by lines d and a are (12 x minus 5) degrees, blank, blank, blank; by lines e and a are blank, (8 x minus 25) degrees, blank, blank. b is parallel to c b is parallel to d b is parallel to e c is parallel to d c is parallel to e d is parallel to e
