As the measure of 2 is 40 degrees, we can say that:
- Angle 3, as it is opposed to the vertex of angle 2, it also have a measure of 40 degrees.
- Angles 1 an 4 are supplementary angles of 2 and 3 respectively, so they have a measure of 180-40=140 degrees.
As AB is parallel to CD, then we have 6 and 7 equal to 2, and 5 and 8 equal to 1.
1. Angle 3: 40 deg
2. Angle 4: 140 deg
3. Angle 6: 40 deg
