Find the primary solution of cosθ=−0.3

⁡

The solution of cos θ = −0.3 is θ = 107.45760312 degrees

Solution:

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
