Is it
A. 10
B.-9
C.3
D.6

Answer:
C. 3
Step-by-step explanation:
You know the angle sum is ...
∠FGT +∠TGH = ∠FGH
You can use this relation with the given values to find x.
90 + (8x +4) = 39x +1
93 = 31x . . . . . . . . . . . . . add -1-8x, collect terms
3 = x . . . . . . . . . . . . . . . . divide by 31
Answer:
C) x=3
Step-by-step explanation:
(39x+1)-90=8x+4
39x+1-90=8x+4
39x-8x-89=4
31x=4+89
31x=93
x=93/31
x=3
