What are the values of a, b, and c in the quadratic equation 0 = one-halfx2 – 3x – 2? a = one-half, b = 3, c = 2 a = one-half, b = –3, c = –2 a = one-half, b = 3, c = –2 a = one-half, b = –3, c = 2

Given: lines a and b are parallel and line c is a transversal. prove: 2 is supplementary to 8 what is the missing reason in the proof? statement reason 1. a || b, is a transv 1. given 2. ∠6 ≅ ∠2 2. ? 3. m∠6 = m∠2 3. def. of congruent 4. ∠6 is supp. to ∠8 4. def. of linear pair 5. ∠2 is supp. to ∠8 5. congruent supplements theorem corresponding angles theorem alternate interior angles theorem vertical angles theorem alternate exterior angles theorem
