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
Like earlier take the bigger shape and divide the smaller one.
8.4 divide by 4 and you get 2.1.
The answer is 4 square root 5 or -4 square root 5
