Answer:

A) ∠DHG = 96°

B) arc EF = 134°

Explanation:

Part A:

As you have shown in your work, angle DHG is supplementary to given angle FHG:

∠DHG = 180° -∠FHG

∠DHG = 180° -84°

∠DHG = 96°

__

Part B:

∠DHG is half the sum of arcs EF and DG.

96° = (1/2)(arc EF + 58°) . . . . . fill in known values

192° -58° = arc EF . . . . . . . . . . multiply by 2, subtract 58°

arc EF = 134°
