Answer:
∠E = 66
d = 47
Explanation:
The sum of angles of a triangle must be 180; thereofre.
[tex]\angle D+\angle E+\angle F=180[/tex]since ∠D = 63 and ∠F = 51, we have
[tex]63+\angle E+51=180[/tex][tex]114+\angle E=180[/tex]subtracting 114 from both sides gives
[tex]\angle E=180-114[/tex][tex]\boxed{\angle E=66}[/tex]which is our answer!
To find the length of d we draw the traingle
