Afunction is created to represent the height above sea level of a mountain climber every hour. what restrictions would be made to the range?

a. the range would only include positive and real number.
b. the range would only include positive integers.
c. the range would only include negative real numbers.
d. the range would include all real number.

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
