When two objects are rubbed together, some negatively charged particles from one object can be transferred to another object. What will happen to the objects if one has more negative charges than the other? A. They will repel each other. B. They will not act differently. C. They will create a spark. D. They will attract each other.

if triangle abc is congruent to triangle def, their interior angles are congruent, because congruent parts of congruent triangles are congruent (cpctc).

that means ∠d is congruent to ∠a; ∠d is equal to 8x - 2.

interior angles of all triangles add to equal 180 degrees, so you can set the sum of these interior angle values equal to 180 and solve for x.

180 = (8x - 2) + 22 + 72

180 = 8x - 2 + 22 + 72

180 = 8x + 92

88 = 8x

11 = x

x = 11

it will give you a job and will make you a better person in the future! : )
