Answer:
(b) 2 1/2
Step-by-step explanation:
The similarity statement lists corresponding vertices in the same order. Corresponding line segments have corresponding end points.
Using the vertices in left-right order, the corresponding line segments are ...
MN : PQ or 5 : x
MO : PR or 4 : 2
NO : QR or 4 1/2 : (no name)
Corresponding segments are proportional (their ratios are equal), so we have ...
5/x = 4/2
5/2 = x . . . . . . multiply by x/2
The length of x is 2 1/2.
