Answer:
m∠1= 157°(Angles 1 and 7 are alternate exterior.)
m∠2= 23°(Angles 8 and 2 are alternate exterior.)
m∠3= 157°(Angles 1 and 3 are vertical.)
m∠4= 23°(Angles 6 and 4 are alternate interior.)
m∠5= 157°(Angles 5 and 7 are congruent.)
m∠6= 23°(Angles 6 and 8 are vertical.)
m∠7= 157°(Angles 7 and 8 are on a straight line.)
