#### 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 $RP$:
$RP = \frac{MP}{2} = \frac{10.6}{2} = 5.3$
