CF = CD + DF (since D is simply a point on the line, and C to that point added onto F to that point is CF), so 4y-9+2y-7=14. Adding it up, we get 6y-16=14 and adding by 16 we get 30=6y. Dividing both sides by 6, we get y=5. Plugging that into DF, we get 10-7=DF=3
Angle C and E are supplementary angles and when added together equal 180 degrees.
To find E, subtract C from 180.
E = 180 - 147 = 33
Angle E = 33 degrees.
I graphed this on a calculator sorry if it is not helpful.
I think it’s 25x if not send the equation answers
