10-69.

First decide if the triangles below are similar. Then, if they are similar, use the information in each diagram to solve for $x$.

1. If only two pair of corresponding sides have equal ratios, can you conclude that the triangles are similar?

1. Careful!

The two triangles are similar (by $\text{AA}\sim$).

Draw two separate triangles, then write a proportion and solve for $x$.

$\frac{12}{7}=\frac{16}{x}$
