The solution of cos θ = −0.3 is θ = 107.45760312 degrees
<em><u>Solution:</u></em>
Given that we have to find the primary solution of
To solve this equation, you must find the unknown (theta)
Use the inverse of cosine (Arccos) to find the angle measurement (in degrees) of theta
We know that arccos (-0.3) = 107.45760312 degrees
[ If you reference a unit circle or use a calculator ]
Therefore solution of cos θ = −0.3 is θ = 107.45760312 degrees
