Using the triangle sum theorem:


\begin{gathered} m\angle L+m\angle K+20=180 \\ 2m\angle L=180-20 \\ 2m\angle L=160 \\ m\angle L=(160)/(2) \\ m\angle L=80 \end{gathered}

Using the exterior angle theorem:


\begin{gathered} m\angle E=m\angle L+m\angle J \\ m\angle E=80+20 \\ m\angle E=100 \end{gathered}

Answer:

100
