To find the measure of angle 2, we can use the properties of parallel lines and the angles formed by a transversal.
Given that lines M and N are parallel and angle 5 measures 115°, we can infer the following:
- Angle 5 (115°) and angle 2 are corresponding angles. Therefore, they are equal in measure since they occupy the same relative position at each intersection of the transversal with the parallel lines.
Therefore, angle 2 is also 115°.
So the answer is:
115°
