Answer:
A
Step-by-step explanation:
it cant be any other one
7.2 is the answer i hope this helps!
ON = 8x • 8
LM = 7x + 4
NM = x - 5
OL = 3y - 6
OL is congruent & parallel to NM
LM is congruent & parallel to ON
So,

Simplify

subtract 7x from both sides

divide 57 from both sides

Substitute x into equations




NM & OL = -28/57
ON & LM = 4 + (28/57)
