Question

Given: line BC is parallel to line ED m∠ABC = 70° m∠CED = 30° Prove: m∠BEC = 40°

Answer 1

Answer:

True, m$\angle$BEC=40º

Step-by-step explanation:

Given that $\overleftrightarrow{BC} || \overleftrightarrow{ED}$, we know that $\angle$ABC = $\angle$BED = 70º because of corresponding angle theorem.

Furthermore,

$\angle$BED = $\angle$BEC + $\angle$CED

Given that $\angle$CED = 30º, we can find $\angle$BEC.

70º=30º + $\angle$BEC

$\angle$BEC = 40º
