The two triangles are similar, What is the length of DE?

horsena [70]

<h2>Answer:</h2>

This is easy. All you need to do is set up a <u><em>proportional relationship</em></u>.

A proportional relationship uses variables to show similarities, in this case, in triangles.

$\frac{2}{3} = \frac{x}{6.3}\\\\3x = 12.6\\\\x = 4.2$

<u><em>x</em></u> represents the missing side.
