Answer:
[tex]170[/tex]
Step-by-step explanation:
The angle 42x+1 is the inscribed angle of Arc WX. This means Arc WX is twice of 42x+1.
[tex]wx = 2(42x + 1)[/tex]
We can add up that and the other arcs to 360.
[tex]2(42x + 1) + 29x - 1 + 65x + 3[/tex]
[tex]84x + 2 + 29x - 1 + 65x + 3 = 360[/tex]
[tex]178x + 4 = 360[/tex]
[tex]178x = 356[/tex]
[tex]x = 2[/tex]
Plug in 2 for WX.
[tex]84(2) + 2 = 170[/tex]
