To determine the measure of angle 2 when angles 5 and 2 are positioned along parallel lines M and N, we need to understand the relationships between the angles.
Since lines M and N are parallel, according to the corresponding angles theorem, angle 2 and angle 5 will be equal if they are corresponding angles. Thus:
- If angle 5 is 115°, then angle 2, being a corresponding angle, will also be:
\[ \text{Angle 2} = 115° \]
Therefore, the measure of angle 2 is 115°.
Response: 115°
