Answer:

Hey friend,

Here's your answer

l and m are parallel lines

and n is the transversal so,

angle 1= angle 3(vertically opposite angles

angle 3=60°

angle 4=angle 8(corresponding angles)

angle 2=angle 6(corresponding angles)

angle 8 and angle 6=120°

angle 3= angle 5(alternate interior angles)

angle 5=60°

Angle 5=angle 7(vertically opposite angles)

angle 7=60°
