Answer 1

`170`

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)`

We can add up that and the other arcs to 360.

`2(42x + 1) + 29x - 1 + 65x + 3`

`84x + 2 + 29x - 1 + 65x + 3 = 360`

`178x + 4 = 360`

`178x = 356`

`x = 2`

Plug in 2 for WX.

`84(2) + 2 = 170`
