(01.07 mc) lines bc and ed are parallel. they are intersected by transversal ae, in which point b lies between points and e. they are also intersected by transversal ec. angle abc measures 70 degrees. angle ced measures 30 degrees. given: line bc is parallel to line ed m∠abc = 70° m∠ced = 30° prove: m∠bec = 40° statement justification line bc is parallel to line ed given m∠abc = 70° given m∠ced = 30° given m∠bec + m∠ced = m∠bed angle addition postulate m∠bec + 30° = 70° substitution property of equality m∠bec = 40° subtraction property of equality which of the following accurately completes the missing statement and justification of the two-column proof? m∠abc = m∠ced; corresponding angles theorem m∠abc = m∠ced; alternate interior angles theorem m∠abc = m∠bed; corresponding angles theorem m∠abc = m∠bed; alternate interior angles theorem

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

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: just trying to get points sorry : (

what statement? is there an image?
