Why did tacitus regard germanic people as distinctly inferior to romans?

Laziness, drunkness and barbarism.

Explanation:

In the year 98 after Christ, Tacitus wrote the book germania, in which he worked on the German tribes.

He wrote about some positive characteristics of the people from Germanic tribes, for example, monogamy and their marriage fidelity, but crictized them for laziness, drunkness and barbarism.

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
