Since E is the midpoint, DE and EF are the same length.
Set the equation DE and EF equal to each other and solve for x.
2x + 4 = 3x - 1
x = 5
Then plug in 5 to find the length.
DE = 2(5) + 4 = 14
EF = 3(5) - 1 = 14
DF = DE + EF = 28
Answer:
1 7/100
Step-by-step explanation:
Let the second side be equal to x
Then the first side is x-5
The third side will be x-5-2 = x-7
Therefore you add all the following sides and equate it to 42 yards. Ie x+x+5+x-7 = 42
3x=44
X= 44/3
Therefore the second sides length is 44/3
The first sides length is 44/3 -5 = 29/3
The third side is 44/3 -7 = 23/3
There’s tutors for math i just asked a tutor for help lol
