The angle that is an exterior angle to 7 will be angle 1.
How to illustrate the angle?
Alternate exterior angles are the pair of angles on the outer side of the two parallel lines but on the opposite side of the transversal
If the transversal cuts across parallel lines (the usual case) then exterior angles are supplementary added to 180°
Therefore, the angle that is an exterior angle to 7 will be 1.
