There are various kinds of social motivation. One type of social motivation is the need to affiliate, or belong to a group. How can evolutionary theory, drive-reduction theory, and arousal theory explain our need for affiliation?

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

the answer is c teaching students and collaborating with teachers on instructional content.
