Answer 1

C) x=3

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

Answer 2

C. 3

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
