Ответ:
EF = 13
Step-by-step explanation:
Opposite sides of a parallelogram are of equal lengths (properties of a parallelogram)
Therefore,
EF = DG
x + 3 = 2x - 7 (substitution)
Collect like terms
x - 2x = -3 - 7
-x = -10
Divide both sides by -1
x = -10/-1
x = 10
✔️EF = x + 3
Plug in the value of x
EF = 10 + 3
EF = 13
