✔️Answer:

Arccos (-0.5)= 120 degrees

✔️Explanation:

To solve this equation, you must find the unknown (theta).

cosθ= -0.5

Use the inverse of cosine (Arccos) to find the angle measurement (in degrees) of theta.

θ = arccos (-0.5)

If you reference a unit circle or use a calculator, that would be 120 degrees.
