Final answer:
The angle measure of a blue wedge is 14°.
Step-by-step explanation:
To find the angle measure of a blue wedge, we need to subtract the measure of the yellow wedge in one earring from the measure of the yellow wedge in the other earring.
The earring with the 25° yellow wedge has a blue wedge with an angle of 25°.
The earring with the 14° yellow wedge has a blue wedge with an angle of 14°.
Therefore, the angle measure of a blue wedge is 14°.
