Which lines can you conclude are parallel given that m∠7 + m∠11 = 180? justify your conclusion with a theorem. line a is parallel to line b by the converse of the alternate interior angles theorem. line a is parallel to line b by the converse of the same-side interior angles theorem. line c is parallel to line d by the converse of the alternate interior angles theorem. line c is parallel to line d by the converse of the same-side interior angles theorem.7 + m∠

Line a is parallel to line b by the Converse of the Same-Side Interior Angles Theorem.

Step-by-step explanation:

find out the statement that conclude are parallel given that m∠7 + m∠11 = 180

angle 7 and 11 are the consecutive interior angles . that is same side interior angles.

angle 7 and 11 are the consecutive interior angles and they are supplementary when the lines are parallel.

Line a is parallel to line b by the Converse of the Same-Side Interior Angles Theorem.

answer is x<

its a straight line parallel to the time axis
