The measure of arcDG from the given diagram is 110 degrees
According to the circle theorem that states "the angle at the centre of the circle is twice the angle at the circumference;
From the given diagram,
Angle at the circumference = 55 degrees
Angle at the centre = arc DG
According to the theorem;
[tex]arc DG = 2m\angle DHG\\arc DG =2(55)\\arc DG =110^0[/tex]
Hence the measure of arcDG from the given diagram is 110 degrees
