Answer:

∠FDG = 122° (D)

Step-by-step explanation:

Find attached the diagram obtained from the given information

m∠FHG = 61°

m∠FHG is an inscribed angle and ∠FDG is a central angle

An inscribed angle is half of a central angle.

m∠FHG = 1/2 × ∠FDG

To determine the measure of ∠FDG,

∠FDG = 2× m∠FHG

∠FDG = 2× 61°

∠FDG = 122°
