Triangle LMN is similar to triangle RST. What is the value of LN if RT is 9,inches MN is 21 inches, and ST is 7 inches?

Respuesta :

LN = 27 inches

Since the triangles are similar then the ratios of corresponding sides are equal.

[tex]\frac{LN}{9}[/tex] = [tex]\frac{21}{7}[/tex] ( cross- multiply )

7LN = 189 ( divide both sides by 7 )

LN = 27
