GUYS sends people to delete answers that are not school-related or are not correct, and sometimes they go crazy. This has happened to me before also, but not this bad, they only deleted my non-school-related questions/answers.

yup

Thanks for letting me know! Im new so i dont know alot about this.

Explanation:

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
