Answer:
Angle 5 is 107 degrees
Angle 8 is 7s degrees
Step-by-step explanation:
First find angle 5. Since the lines are parallel and cut by a transversal, we can say that Angle 3 and Angle 5 are congruent (same measure) since they are alternate interior angles.
Since Angle 3 is 107 degrees, Angle 5 would also be 107 degrees.
Angle 8 is supplementary to Angle 5.
Angle 5 + Angle 8 = 180
Since we know Angle 5 is 107: 107 + Angle 8 = 180
Angle 8 would then be 73 degrees.
