Answer:
∠ G = 85°
Step-by-step explanation:
the inscribed angle DGF is half the measure of its intercepted arc DF
the sum of the arcs in a circle = 360° , then
DF + FG + GD = 360° , that is
DF + 70° + 120° = 360°
DF + 190° = 360° ( subtract 190° from both sides )
DF = 170° , then
∠ G = [tex]\frac{1}{2}[/tex] × 170° = 85°
