Q. 0∘≤θ≤180∘0^\circ\leq\theta\leq180^\circ. Find the value of θ\theta in degrees. \newlinecos⁡(θ)=−2/2\cos(\theta)= - \sqrt{2}/ 2
  1. Recognize angle values: Recognize the specific angle values for cosine function where the result is −2/2-\sqrt{2}/2.
  2. Check angle range: Check if 135∘135^\circ fits within the given range 0∘≤θ≤180∘0^\circ\leq\theta\leq180^\circ.
