Which equation can you use to solve for x? x + 56 = 180 x + 146 = 180 180−x=146 x + 56 = 146 the figure contains a pair intersecting lines. one of the four angles formed by the intersecting lines is labeled 146 degrees. the angle opposite and not adjacent to this angle is broken into two smaller angles by a ray that extends from the point where the two lines intersect. one of these smaller angles is labeled 58 degrees, and the other smaller angle is labeled x degrees.

The correct question is

see the picture attached to better understand the problem

we know that
angle 146° and angle (56°+x°) area equal -----> by vertical angles
so
146=56+x
therefore

the answer is
x + 56 = 146
