If r= 3 cm, p = 2.4 cm, q = 1.8 cm, and m= 4.35 cm, what is the measure of n?

Answer:
C
Step-by-step explanation:
given the triangles are similar then the ratios of corresponding sides are in proportion, that is
[tex]\frac{LM}{PR}[/tex] = [tex]\frac{LN}{PQ}[/tex] ( substitute values )
[tex]\frac{n}{1.8}[/tex] = [tex]\frac{4.35}{3}[/tex] ( cross- m ultiply )
3n = 7.83 ( divide both sides by 3 )
n = 2.61 cm
