What contributed to the decline of structuralism in the early history of psychology? O It depended on natural selection, which was not well accepted until after Darwin made it famous.
O It was limited as a means of scientific discovery due to its reliance on introspection
O Confirming its conclusions relied on technology that had not been discovered yet.
O It could not be applied to internal thoughts and processes.

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
