What are the measures of angles a, b, and c? show your work and explain your answers.

two straight lines intersect at a point to form angle a. the measure of the angle opposite to angle a is 30 degrees. angle a is the angle of a right triangle having another angle equal to b. a triangle with one angle labeled c is on the left of the figure. the angle adjacent to c is labeled 75 degrees.

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
