<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.

Serhud [2]

Answer:

Step-by-step explanation:

12.9 + 10.2x = 35.1

10.2x = 35.1 - 12.9

10.2x = 22.2

x = 22.2/10.2

x= 222/102 = 111/51

x= 2\dfrac{9}{51}
