How can political, economic, cultural or technological changes challenge state sovereignty? If you can please answer in 4-6 sentences.

The growing challenge to state sovereignty around the world seems to originate from the inability of the modern-state to navigate between the power of global networks and the challenges raised through the increase in ethno-political conflict, the expansion of terrorism, the growth of sophisticated weaponry production

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
