• perpendicular line

If angle 8 is 63 degrees, how many degrees is angle 2?

• 63 degrees because angle 8 & 2 are alternate exterior angles.
• 117 degrees because angle 8 & 2 are supplementary.
• 63 degrees because angle 8 & 2 are vertical angles.
• 117 degrees because angle 8 & 2 are same side exterior angles.
