Answer:
Option C
Step-by-step explanation:
From the question we are told that:
[tex]m \angle \theta=120[/tex]
Generally the angle of inclination is [tex]\theta[/tex]
[tex]\theta =180-120[/tex]
[tex]\theta=60[/tex]
Generally the equation for x is mathematically given by
[tex]x=cos60\textdegree *1[/tex]
[tex]x=\frac{1}{2}[/tex]
Since x exists in the second quadrant
Therefore the value of x in simplest form is
[tex]x=-\frac{1}{2}[/tex]
Option C
