ABC ~ LMN, AB = 18, BC = 12, LN = 6. What is the scale factor of ABC to LMN?

a) 9/2

b) 2/1

c) 3/2

d) 3/1

B because the square root of a squared and b squared is = c squared, therefore, meaning if you have side c and b for triangle ABC you'll do 12"2+x=18'2

which will approximately be 13.42. you put 13.42/6 = 2/1
