Answer: ∠E
Step-by-step explanation:
The included angle for [tex]\overline{DE}[/tex] and [tex]\overline{FE}[/tex] is [tex]\angle{E}[/tex].
The included angle for any two lines or line segments is represented by the common vertex point.
For example : The included angle for [tex]\overline{AB}[/tex] and [tex]\overline{BC}[/tex] is [tex]\angle{B}[/tex] [Since B is the common end point in [tex]\overline{AB}[/tex] and [tex]\overline{BC}[/tex] ]
Similarly, the included angle for [tex]\overline{DE}[/tex] and [tex]\overline{FE}[/tex] is [tex]\angle{E}[/tex] (Since E is the common vertex in [tex]\overline{DE}[/tex] and [tex]\overline{FE}[/tex] )
