Tresset [83]

Answer:

Step-by-step explanation:

Since, triangle ABC is the enlargement of triangle XYZ.

$\therefore \triangle ABC \sim \triangle XYZ$

So, corresponding sides of both the triangles would be in proportion.

$\therefore \frac{x}{6}=\frac{25}{10}$

$\therefore x= \frac{6\times 25}{10}$

$\therefore x =\frac{150}{10}$

$\therefore x = 15$
