Problem of the Week
Problem C
Angled

Line segments $AB$ and $CD$ are parallel, with $AB$ above $CD$. Point $J$ lies above $AB$, and points $E$ and $F$ lie on $CD$, with $E$ to the left of $F$, so that $JE$ intersects $AB$ at $G$ and $JF$ intersects $AB$ at $H$.

If $\mathrm{\angle }CEG=110\mathrm{°}$ and $\mathrm{\angle }GHF=122\mathrm{°}$, determine the measure of $\mathrm{\angle }GJH$.
