standard_description: Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.
problem_activity: $${\overline{AD} \parallel \overline{BC}}$$
and
$${\angle EJB}$$
is supplementary to
$${\angle JBK}$$
. Prove that
$${\overline {AD} \parallel \overline{JE}}$$
.
