Answer:

Option C

Step-by-step explanation:

From the question we are told that:

$m \angle \theta=120$

Generally the angle of inclination is $\theta$

$\theta =180-120$

$\theta=60$

Generally the equation for x is mathematically given by

$x=cos60\textdegree *1$

$x=\frac{1}{2}$

Since x exists in the second quadrant

Therefore the value of x in simplest  form is

 $x=-\frac{1}{2}$

Option C
