Answer

(a) $RN = 7.3$ (b) $RP = 5.3$

Work Step by Step

(a) The diagonals of a parallelogram bisect each other. Therefore the point R is the midpoint of $\overline{QN}$ We can find $RN$: $RN = QR = 7.3$ (b) The diagonals of a parallelogram bisect each other. Therefore the point R is the midpoint of $\overline{MP}$ We can find $RP$: $RP = \frac{MP}{2} = \frac{10.6}{2} = 5.3$
