State if the triangles in each pair are similar. If so, state how you know they are similar andcomplete the similarity statement. 3)

In option 3, both triangles are similar. Let's take a look at the ratio between the two sides given in each one:
For MLK:
[tex]\frac{77}{143}=\frac{7}{13}[/tex]For QRS:
[tex]\frac{28}{52}=\frac{7}{13}[/tex]And since both share the same 66° angle, they're similar
