The answer is A. 13.



Hope this helps :)

Answer:

Option A

[tex]w=13\°[/tex]

Step-by-step explanation:

we know that

m∠FGK=[tex]5w+5[/tex]

m∠FGK=[tex]x[/tex]

so

[tex]x=5w+5[/tex] ------> equation A

m∠HGK=[tex]4w+8[/tex]

m∠HGK=[tex]y[/tex]

so

[tex]y=4w+8[/tex] ------> equation B

m∠FGH=[tex]130\°[/tex]

m∠FGH=[tex]x+y[/tex]

so

[tex]x+y=130\°[/tex] -----> equation C

Substitute equation A and equation B in equation C

[tex][5w+5]+[4w+8]=130\°[/tex]

solve for w

[tex][9w+13]=130\°[/tex]

[tex]9w=(130-13)\°[/tex]

[tex]w=(117)\°/9[/tex]

[tex]w=13\°[/tex]
