The Correct Answer and Explanation is: To find the exact value of cos⁡(−195∘)\cos(-195^\circ)cos(−195∘) using a sum or difference formula, we can break the angle into two components whose cosine values are easier to calculate. Let’s use the sum formula for cosine: cos⁡(A+B)=cos⁡(A)cos⁡(B)−sin⁡(A)sin⁡(B)\cos(A + B) = \cos(A)\cos(B) – \sin(A)\sin(B)cos(A+B)=cos(A)cos(B)−sin(A)sin(B) In this case, we can express −195∘-195^\circ−195∘
