Answer:
(4) QR/7 = 14/16
Explanation:
Given that Triangle MNP is similar Triangle QRS, then MN is proportional to QR, NP is proportional to RS, and MP is proportional to QS.
This proportions can be written as follows:
QR = k*MN or k = QR/MN = QR/14
RS = k*NP or k = RS/NP = RS/8
QS = k*MP or k = QS/MP = 7/16
where k is some constant. Therefore:
QR/14 = 7/16 or QR/7 = 14/16
