Answer:

i) angle 3 is 120°

ii) angle 3 + angle 4 = 180° as both angles make up a staright line

∴ angle 4 = 180° - angle 3 = 180° - 120° = 60°

iii) angle 6 = angle 3 = 120° as they are opposite interior angles

iv) angle 6 + angle 8 = 180° as both angles make up a straight line

∴ angle 8 = 180° - angle 6 = 180° - 120° = 60°

Step-by-step explanation:

i) angle 3 is 120°

ii) angle 3 + angle 4 = 180° as both angles make up a staright line

∴ angle 4 = 180° - angle 3 = 180° - 120° = 60°

iii) angle 6 = angle 3 = 120° as they are opposite interior angles

iv) angle 6 + angle 8 = 180° as both angles make up a straight line

∴ angle 8 = 180° - angle 6 = 180° - 120° = 60°
