<h2>Here we go ~ </h2>
According to given figure,


[ By linear pair ]

now, we can see that :

[ By Exterior angle property of Triangle ]


It's C because the equations are similar
Since all triangles equal 180 degrees. You will subtract (128 + 23) from 180.
180 - 146 is 34 degrees.
x=34
X= - 7/2
Hope this helps! :)
