<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.

If 2 angles have the same angle measure they are said to be what
DanielleElmas [232]

2 angles that have the same angle measure are congruent.

Given that the two angles have the same angle measure.

Congruence is a term reserved for geometry. Two metrics are congruent when you can perfectly map to each other by mirroring, rotating, and translating without distortion.

We know that two shapes or objects are congruent if they have the same shape and the same size. For two angles to be congruent, they must coincide when they are overlapped. This is only possible if the two angles are equal.

Therefore, if two angles have the same measure, then they are said to be congruent.

both of these are correct just the matter of fact of what way your teacher wants you to use :)
