Answer:
Angle 3 = 23 degrees Angle 8 = 157 degrees
Step-by-step explanation:
Since Angle 2 and Angle 3 are vertical angles, they have the same value.
As you see for Angle 8, Angle 8 is vertical angles with Angle 5.
Angle 5 corresponds with Angle 1 which is the same value since these lines are parallel.
Angle 1 and Angle 2 added together will have a sum of 180.
So substitute Angle 5 for Angle 1.
Angle 5 + 23 =180
Angle 5 = 157 degrees
And we know Angle 5 = Angle 8
So Angle 8 = 157 degrees.
