Answer:
angle FXG is congruent to angle IXJ or JXI. GHI is 81°
Explanation:
Angle FXG is congruent to angle IXJ because the two are vertical angles. (Vertical angle theorem)
FXG + GXH = FXH
Substitute the given values given:
49 ° + GXH = 130°
Subtract 49 both sides
49 - 49 + GXH = 130 - 49
GXH = 81°
