Answer:
3
Step-by-step explanation:
Since we know QR and RS are the same, we can add them together
6 + 6 = 12
Since the whole line is 15 we subtract 12 from 15
15 - 12 = 3

Triangles MNP & MAB are similar (NP//AB & Angle A= Angle N (correspondent) Same for P & B
We know that MA = 67.2 -3.2 = 35.2
Since Triangles MNP & MAB are similar , then we can write the following ratio:
MN/MA=MP/MB or 67.2/35.2 =81.9/x
& x= 43 m
