What is the similarity statement?

• <FGH

• △GFH

• △FGH

• <GFH

• 12

• 8

• 7.2

• 6

Answer explanation

Use alternate interior angles to find out which angles and sides correspond.  Then,  $\frac{x+4}{x}=\frac{12}{7.2}$  

Find the value of y in the figure.

• 5

• 4

• 8

• 7

Answer explanation

$\frac{y+3}{6}=\frac{12}{9}$ or $\frac{y+3}{12}=\frac{6}{9}$
