Answer:
![170](https://tex.z-dn.net/?f=170)
Step-by-step explanation:
The angle 42x+1 is the inscribed angle of Arc WX. This means Arc WX is twice of 42x+1.
![wx = 2(42x + 1)](https://tex.z-dn.net/?f=wx%20%3D%202%2842x%20%2B%201%29)
We can add up that and the other arcs to 360.
![2(42x + 1) + 29x - 1 + 65x + 3](https://tex.z-dn.net/?f=2%2842x%20%2B%201%29%20%2B%2029x%20-%201%20%2B%2065x%20%2B%203)
![84x + 2 + 29x - 1 + 65x + 3 = 360](https://tex.z-dn.net/?f=84x%20%2B%202%20%2B%2029x%20-%201%20%2B%2065x%20%2B%203%20%3D%20360)
![178x + 4 = 360](https://tex.z-dn.net/?f=178x%20%2B%204%20%3D%20360)
![178x = 356](https://tex.z-dn.net/?f=178x%20%3D%20356)
![x = 2](https://tex.z-dn.net/?f=x%20%3D%202)
Plug in 2 for WX.
![84(2) + 2 = 170](https://tex.z-dn.net/?f=84%282%29%20%2B%202%20%3D%20170)
Answer:
the answer would 12
Step-by-step explanation:
I think it's C, because first you multiply all the sides which is 112 then multiply by 3 and the answer it's 336 if I'm correct.
