Step-by-step explanation:
The Triangle Midsegment Theorem:
ac = 2df = 34
Answer:
I just solved it in that attachment
Walking trails AC and BD represent the diagonals of the parallelogram ABCD. As known the diagonals of the parallelogram bisects each other.
Then
Since DE=BE, then
y+2=3y-4,
2y=6,
y=3.
And BD = y+2+3y-4=3+2+9-4=10 miles.
Since y=3 miles and AE=CE, then
AC=2CE=2(2y-3)=2(6-3)=6 miles.
The sum of the lengths of the two trails is
AC+Bd=10+6=16 miles.
Answer: correct choice is C
