Answer: [tex]125^{\circ}[/tex]

Step-by-step explanation:

Angles that form a straight angle are supplementary, so:

[tex]m\angle 1+m\angle 2=180^{\circ}\\ \\ 55^{\circ}+m\angle 2=180^{\circ}\\ \\ m\angle 2=\boxed{125^{\circ}}[/tex]

Since the angles are supplementary, they add up to 180

So you would subtract 180-55 which equals 125
