since AHE is a straight line the angle would be 180°, the angle EHF would be 180-(80+56) which means the EHF would be 44°
BHC=GHF so it will be 80°
EHF=AHB so it’ll be 44°
now we only have DHE, since all the angels are around one point that means their sum is equal to 360°, so DHE is equal to 360-(44-80-80-44-56-22) which will equal to 34°.
