What is the length of side angle AB of parrellelogram ABCD ?

zavuch27 [327]

$\boxed{x=4cm}$

<h2>Explanation:</h2>

A parallelogram is a quadrilateral that has two pair of opposite sides and each pair measure the same. In order to illustrate this problem, see the figure below. Here we know some facts:

Side AB measures x cm
Side DC measures 4 cm

$\overline{AB}=\overline{DC} \\ \\ \boxed{x=4cm}$
