Answer
Angle 1 = 103°
Step-by-step explanation
Vertical angles are angles that are directly opposite each other when two straight lines cross. They are known to be equal to each other.
So, if Angle 1 and Angle 2 are vertical angles,
Angle 1 = Angle 2
If Angle 2 = 103°
Then,
Angle 1 = Angle 2 = 103°
