✓ In PQR ,P-M-Q and P-N-R IF PQ-18, PM - 12, PR-9 and NR =_______ Then MN||QR .
[Answer the question in 1min and I will mark u as brainliest]​

Answer 1

Step-by-step explanation:

PQ=18cm

P-M-Q. hence PM+MQ=PQ

12+MQ=18

MQ=18-12=6

lly,. let NR=x and PN=9-x

In ∆PQR MN||QR

HENCE BY BASIC PROPORTIONALITY THEOREM

PM/MQ=PN/NR

12/6= 9-x/x

2x=9-x

2x+x=9

3x=93

x=3

hence NR= 3 units
