That's correct. Now you gotta plug in -5 in for x and get both angles.
Answer:

Step-by-step explanation:
The angle 42x+1 is the inscribed angle of Arc WX. This means Arc WX is twice of 42x+1.

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





Plug in 2 for WX.

Answer:
a = 2

Hope this helps and have a nice day :)
Answer:
X = 66
Step-by-step explanation:
A straight line is equal to 180 degrees so if you have one side of that line you can figure out the inside angle.
Now that you have two of the angles inside the triangle add them up. All the interior angles of a triangle will add to 180. So add up 38 and 76 to get 114. Now do 180 - 114, you should get 66
so x = 66
