That is:
2x^2+5(9x-3)×2
2x^2+(45x-15)×2
2x^2+90x-30
2(x^2+45x-15)
When there is a midpoint in a line segment, the two segments that are then produced have to be equal. So that means that because E is a midpoint of DF, DE=EF.
Set up the equation.
DE=EF
2x+4=3x+1
Then solve for x.
x=3
Then plug it back in the equation to find DE and EF.
DE=2x+4=2(3)+4=10
Because DE=EF then EF is also 10.
DF is made from the addition of DE and EF so DF is twice EF.
DF= 20
DE= 10, EF= 10, DF= 20
Hope this helps.
Here, EJI + FJE = 180 [ Linear-Pair Equation ]
FJE + 135 = 180
FJE = 180 - 135
FJE = 45
Now, FJH + FJE = 180 [Linear-Pair Equation ]
FJH + 45 = 180
FJH = 180 - 45
FJH = 135
Hope this helps!
