Let's assume that the measure of angle 2 is x°. Since angle 2 and angle 4 are a vertical pair, they have the same measure. Therefore, angle 4 = x° as well.
The sum of their measures is equal to 110°, so we can create the equation:
x° + x° = 110°
Simplifying, we get:
2x° = 110°
Dividing both sides of the equation by 2, we find:
x° = 55°
Therefore, angle 2 = angle 4 = 55°.
