Answer
Angle 6 = 54°
Step-by-step explanation
To answer this question, we need to first explain the possible re;lationship between Angle 3 and Angle 6; alternate angles.
Alternate angles are angles that are in opposite positions relative to a transversal intersecting two lines. If the two lines are parallel to each other, then alternate angles are equal.
And we can easily see that Angle 3 and Angle 6 are alternate angles.
Angle 3 = Angle 6 = 54°
