Answer:
x = 36
Step-by-step explanation:
the 3 angles form a straight angle and sum to 180°
sum the 3 angles and equate to 180
3x + x + x = 180 , that is
5x = 180 ( divide both sides by 5 )
x = 36
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.
