To prove that lmn~xyz by the sss similarly theorem using the information provided in the diagram, it would be enough additional information to know that.

a) lm is 3 units and xz is 5 units
b) lm is 4 units and xz is 6 units
c) lm is 5 units and xz is 3 units
d) lm is 6 units and xz is 4 units

I believe the answer would be B because it makes the most sense putting the figures scaled in my head with the already designated lengths

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
