Answer:
B. 38°
Explanation:
From the given figure, angles x and 142 degrees are on a straight line.
The sum of angles on a straight line is 180 degrees, therefore:
[tex]x+142\degree=180\degree[/tex]
Next, we solve the equation for x:
[tex]\begin{gathered} x=180\degree-142\degree \\ x=38\degree \end{gathered}[/tex]
The correct choice is B.
