Answer 1

Answer:

$\frac{16}{21}=\frac{8}{10.5}$

or

$\frac{16}{8}=\frac{21}{10.5}$

Step-by-step explanation:

we know that

If two figures are similar then the ratio of its corresponding sides is proportional

In this problem

triangle YPQ and triangle YXZ are similar by AA Similarity Theorem

so

$\frac{YP}{YX}=\frac{YQ}{YZ}$

substitute the given values

$\frac{16}{21}=\frac{8}{10.5}$

Rewrite

$\frac{16}{8}=\frac{21}{10.5}$
