Answer
$\angle$ACB and $\angle$KOL
$\angle$HNE and $\angle$ENF
Work Step by Step
The angles $\angle$ACB and $\angle$KOL are supplementary angles.
$\angle$ACB + $\angle$KOL = 120$^{\circ}$ + 60$^{\circ}$
= 180$^{\circ}$
The angles $\angle$HNE and $\angle$ENF are supplementary angles.
$\angle$HNE + $\angle$ENF = 77$^{\circ}$ + 103$^{\circ}$
= 180$^{\circ}$
