Answer:

x=5

Step-by-step explanation:

3x^2=15x

Subtract 15x from both sides

Find the value of x that makes the two triangles equal

Leona [35]

Answer:

5

Step-by-step explanation:

$\triangle CDE \sim\triangle FGH...(given)$

$\therefore \frac{CD}{FG}=\frac{CE}{FH}...(csst)$

$\therefore \frac{4x}{28}=\frac{25}{35}$

$\therefore \frac{x}{7}=\frac{5}{7}$

$\therefore x=\frac{7\times 5}{7}$

$\therefore x=5$
