Answer:
∠ GFH = 59°
Explanation:
∠ EFH is composed of ∠ EFG and ∠ GFH , that is
∠ EFG + ∠ GFH = ∠ EFH ( substitute values )
8x - 4 + 5x + 14 = 127 ( collect like terms on left side )
13x + 10 = 127 ( subtract 10 from both sides )
13x = 117 ( divide both sides by 13 )
x = 9
Then
∠ GFH = 5x + 14 = 5(9) + 14 = 45 + 14 = 59°
