From the given figure we can see that
[tex]m\angle FGH=m\angle FGA+m\angle AGH[/tex]Since mSince mSince m[tex]157=8x+3+42x+4[/tex]Add the like terms on the right side
[tex]157=50x+7[/tex]
Subtract 7 from both sides
[tex]150=50x[/tex]
Divide both sides by 50
[tex]\begin{gathered} \frac{150}{50}=\frac{50x}{50} \\ \\ 3=x \end{gathered}[/tex]
The answer is x = 3
