In a parallelogram the diagonals bisect each other, so RV = TV. Set y + 18 = 3y − 10.
Solve: 18 + 10 = 3y − y → 28 = 2y → y = 14.
Then RV = 14 + 18 = 32, so diagonal RT = 2·32 = 64.
Answer: B.
Solve: 18 + 10 = 3y − y → 28 = 2y → y = 14.
Then RV = 14 + 18 = 32, so diagonal RT = 2·32 = 64.
Answer: B.
