Angle G is a circumscribed angle of circle E.

Circle E is shown. Line segments F E and D E are radii. A line is drawn to connect points F and D. Tangents F G and D G intersect at point G outside of the circle. Angles E B D and F D E have measures of x degrees.

Help me, please!
What is the measure of angle G, in terms of x?

x° + x°
x° + 90°
180° – x°
180° – 2x°
