Question

ΔLNR ~ ΔMNP
LN = 12, MN = 8
NP = 6, NR = x+6
Find NR

Answer 1

Ok, let's get the rule sorted first

Answer 2

The rule says the perimeter ratio of two ST is the same as the ratio of the length, the area ration is sqare that

Answer 3

so your last Q said the ratio of length is 3:4, so perimeter ratio is 3/4 and area is 9/16

Answer 4

For this Q, you have to understnad one thing: the similar notation has to be written so that the two triangles corresponds

Answer 5

In the context of your Q, LNR and MNP are similar, meaning that LN corresponds to MN and NR corresponds to NP

Answer 6

which means LN/MN=NR/NP

Answer 7

now you have the equation and you can solve!

Answer 8

thank you so much for your help.

Answer 9

NP! just tag me when you are in trouble and I'll respond ASAP
