∠5

∠7

135° because corresponding angles are congruent

180° - 135° = 45° becuase corresponding angles are supplimentary

∠1

∠3

∠4

∠6

∠8

40° because they are alternate interior angles and congruent

40° because they are corresponding angles and congruent

140° because they are alternate interior angles and supplimentary

140° because they are vertical angles and supplimentary

∠1

∠3

∠4

∠6

∠7

180° because they are supplimentary angles

128° because they are alternate exterior angles and congruent

42 + 8x = 2 + 12x

2 + 12x + 42 = 8x

42 + 8x + 2 + 12x = 180

42 + 8x = 180
