Answer:
angle 4
Step-by-step explanation:
From the diagram given, we can assume that line L is parallel to line M'
If that is the case hence;
m<5 = m<8 (vertically opposte angle)
Also m<5 = m<4 (alternate exterior angle)
Since <5 = <4, hence <4 = <8 (alternate exterior angle)
According to the question, we can conclude that <4 is the alternate exterior angle with angle 8
