The correct option is A. m∠BEC + 30° =70°; Substitution Property of Equality.

Step-by-step explanation:

Consider the provided information.

line BC is parallel to line ED: Given

m∠ABC = 70°  : Given

m∠CED = 30°  : Given

m∠ABC = m∠BED Corresponding Angles Theorem

m∠BEC + m∠CED = m∠BED Angle Addition Postulate

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

m∠BEC = 40° Subtraction Property of Equality.

We substitute the value of m∠CED=30° that is why it is know as substitution property of equality.

Hence, the correct option is A. m∠BEC + 30° =70°; Substitution Property of Equality.
