$ABC$ is an isosceles triangle where $AB=AC$ and $<A=100 degree$.$D$ is a point on $AB$ such that $CD$ bicects$<ACB$ internally.If $BC=2018$ then $AD+CD=?$.

$\triangle ABC$ is an isosceles triangle where $AB=AC$ and $\angle A=100^{\circ}$.
$D$ is a point on $AB$ such that $CD$ bicects$\angle{ACB}$ internally.
If $BC=2018$ then $AD+CD=?$.
