Circle d is shown with the measures of the minor arcs. which segments are congruent? eh and ef gh and fe fg and eh ef and gf

I can't really answer this problem if we focus only on the given information. However, I found a similar problem to this with a given diagram. This is shown in the picture attached. As you can observe, two arcs have equal measures of 65° and two have measures of 115°. Thus, the congruent arcs are: EH = HG and EF = GF.

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.
