Answer 1

Answer:

b

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{AB}{XY}$ = $\frac{BC}{YZ}$ , substitute values

$\frac{15}{10}$ = $\frac{21}{YZ}$ ( cross- multiply )

15YZ = 210 ( divide both sides by 15 )

YZ = 14 → b
