Question

In Fig 8.116, if l||m||n and ∠1 = 60°, find ∠2

Answer 1

Answer:it would be 120 degree

Step-by-step explanation:

angle 1 + angle 2=60 (corresponding angles)

angle 2 +3 =180          ( angles on a straight line)

therefore angle 3 = 120

angle 3 =4= 120           (adjacent angles)

Answer 2

Answer:

Angle 1=60

Angle 1=Angle3

ang3+4=180

Angle4=120

Angle 4=Angle2(alternate angles)

120deg=120deg
