Answer:
B. 130
Explanation:
Angle AGB is congruent to angle DGE because of vertical angles.
Angle CGD and DGE form a right angle (90)
3x-28+66-x=90
2x+38=90
2x=52
x=26
Angle FGE is also 90 because of vertical angles
Angle AGF is congruent to CGD also because of vertical angles.
Angle CGD = 40
40+90=130
