Answer:
The correct option is the 3rd one
angle 1 = angle 4 = angle 5 = angle 8 = 60 degrees,
angle 2 = angle 3 = angle 6 = angle 7 = 120 degrees
Explanation:
To solve this, we only need to look at the top two angles, 1 and 2
Since line l is a line, angle 1 and 2 must sum to 180,
Since angle 1 = 60 degrees, then,
angle 1 + angle 2 = 180
60 + angle 2 = 180
angle 2 = 120 degrees
the only option that corresponds to this is the third option,
angle 1 = angle 4 = angle 5 = angle 8 = 60 degrees,
angle 2 = angle 3 =
