How does a rise in the “general price level” differ from the increase in the price of one good?

A rise in the general price level would much more bigger than an increase of the price of one good.

Explanation:

The general price level is the overall average price of all goods and services. An increase of one good is just an individual that is part of the general price level.

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
