Describe the broader historical situation in Africa at the time that Jean barbot wrote his book

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

uh cause they want to stop talkin to you (depends if its online)

or if its in real life they just want you to sleep ig

or maybe they jus tired.

but if it's online they prob just saying that cause they dont wanna talk to you or they want u to leave
