Answer:

Option C

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=(1)/(2)`

Since x exists in the second quadrant

Therefore the value of x in simplest form is

`x=-(1)/(2)`
