Which of the following statements best represents a hypothesis?
titanium is one of the strongest minerals.
a system of lenses can be used to improve vision.
atoms that have been combined into molecules can be used to develop medicines.
two objects dropped from the same height will hit the ground at the same time.

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

c) was interpreted by the supreme court in gibbons v. ogden.
