Angles 1 and 7 are alternate exterior angles of a transversal cutting two parallel lines. If m(angle1)=4x+10 and m(angle7)=6x+4, what are the measures of angles 1 and 7? Give a property of angles that helped you solve the problem.
What's confusing me about this problem is the fact that angles 1 and 7 are alternate exterior angles. Is this possible with the two lines being parallel?
