We are given the information about x that
.
We know that [tex]cos x=-\frac{1}{2}[/tex ] is actually the ratio of adjacent side to the hypotenuse. It means that here, adjacent is -1 and hypotenuse is 2.
A negative cosine tells us that the angle is either in Quadrant II or Quadrant III.
So if it is in 2nd quadrant, then x = 120° and if its in 3rd quadrant then x = 240°.
