After taking several assessments and being told that all signs indicate he is perfect in every way for a career as a high school teacher, Mike becomes a high school teacher.
He is miserable. Why is Mike so miserable in a career that psychological assessments
indicated he would be a perfect fit?

Although Mike would have some characteristics that would help him be good in teaching, it's not guaranteed that it will be enjoyable for him. Psychological assessments should be treated as suggestions and not a method to make an important life decision on.

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
