Answer: D. 19

Let x by the length of CG. Since the two bases are parallel, we can create the following equation using proportions:

$\dfrac{63}{21}=\dfrac{57}{x}$

Simplify left side of equation

$3=\dfrac{57}{x}$

Multiply both sides by x

$3x=57$

Divide both sides by 3

$x=19$

Let me know if you need any clarifications, thanks!
