Ineed with my math problem- this might be cheating but eh (it is) anyways- my question is: evaluate 3+11t -9u3+11t−9u3, plus, 11, t, minus, 9, u when t=9t=9t, equals, 9 and u=11u=11u, equals, 11. (sorry this is- complicated.)

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
