Answer:

a) angle 4 = 60°

b) angle 6 = 120°

c) angle 8 = 60°

Step-by-step explanation:

a) angle 4 =

  • angle 3 and angle 4 are on the straight angle and they are both equal 180°

angle 3 = 120

angle 4 = 180 - 120 = 60

a) angle 4 = 60°

b) angle 6 =

  • angle 6 = angle 2 and angle 2 = 120°

b) angle 6 = 120°

c) angle 8 =

  • angle 6 and angle 8 are on the straight angle and they are both equal 180°

angle 8 = 180 - 120 = 60

  • angle 8 = angle 4 and angle 4 = 60°

c) angle 8 = 60°
