Accepted Solution
A:
Problem 1)
Minor arc DG is 110 degrees because we double the inscribed angle (DHG) to get 2*55 = 110
Answer: 110 degrees
=================================================
Problem 2)
Central angle GDC is the same measure as arc GFC. The central angle cuts off this arc.
The arcs GEC and GFC both combine to form a full circle. There are no gaps or overlapping portions.
