Question

Hi Ms or Mr i need help with this problem could you guide me here step by step

Answer 1

When two parallel lines are intercepted by another line, the angles formed between the two lines parallel lines and the one that intercepted them are congruent in alternated sides. This means that the angle AEF is congruent to DFE, Therefore:

`\begin{gathered} \measuredangle DFE=\measuredangle AEF \\ \measuredangle DFE=40 \end{gathered}`

The angle DFE is 40 degrees.
