Answer:

m∠ABC = m∠BED; Corresponding Angles Theorem

Step-by-step explanation:

Given: line BC is parallel to line ED m∠ABC = 70° m∠CED = 30°

Prove: m∠BEC = 40°

Statement Justification

1. line BC is parallel to line ED - Given

2. m∠ABC = 70° - Given

3. m∠CED = 30° - Given

4. m∠BEC + m∠CED = m∠BED - Angle Addition Postulate

5. m∠ABC = m∠BED - Corresponding Angles Theorem

6. m∠BEC + 30° = 70° - Substitution Property of Equality

7. m∠BEC = 40° Subtraction Property of Equality
