Answer:

SAS theorem

Step-by-step explanation:

If $\frac{CE}{CB} = \frac{DC}{AC}$ and m∠ECD = m∠BCA, then the triangles are similar by the SAS theorem.

$\frac{EC}{BC} = \frac{14}{21} = \frac{2}{3}$ $\frac{DC}{AC} = \frac{18}{27} = \frac{2}{3}$

So, $\frac{CE}{CB} = \frac{DC}{AC}$ and m∠ECD = m∠BCA because vertical angles are congruent

Therefore ΔECD is similar to ΔBCA by SAS theorem

$\rm \looparrowright - \frac{1}{4} (8 - 4 + 20x)$

Subtract the numbers

$\rm \looparrowright - \frac{1}{4} (4+ 20x)$

Factor out 4 from the expression

$\rm \looparrowright - \frac{1}{ \cancel4} \times \cancel4(1 + 5x)$

$\rm \looparrowright - (1 + 5x)$

When there is a - in front of an expression in parentheses, change the sign of each term in the expression to -

$\rm \looparrowright - 1 - 5x$
