Answer:
x = 45
Explanation:
If we assume that ray GJ lies between rays GF and GH, then the angle sum theorem tells us ...
∠FGH = ∠FGJ +∠JGH
140° = 95° +x°
45° = x° . . . . . . subtract 95° from both sides
x = 45
_____
Alternate solution
There is an alternate solution if ray GF lies between ray GH and ray GJ.
∠JGH = ∠FGJ +∠FGH
x° = 95° +140°
x° = 235°
x = 235
Without some additional information, we cannot tell which assumption we should make about the geometry.
