Dear student,∠1=120°∠1=∠3=120°       (vertically opposite angles)∠1+∠2=180°        (linear pair)120°+∠2=180°∠2=60°∠2=∠4=60°         (vertically opposite angles)∠1=∠5=120°       (corresponding angles)∠5=∠7=120°       (vertically opposite angles)∠4=∠6=60°          (Alternate interior angles)∠6=∠8=60°          (vertically opposite angles)Therefore,∠1=120°∠2=60°∠3=120°∠4=60°∠5=120°∠6=60°∠7=120°∠8=60°Regards

In the given figure, l ? m and t is a transversal. If ?1 = 120?, find measure of each of the angle ?2, ?3, ?4 ?5, ?6,?7 and? 8.
