Q: If cos(θ) = 0.707, what is θ? (2020)
Solution:
cos(45°) = √2/2 ≈ 0.707, so θ = 45°.
Steps: 5
Show Steps
Step 1: Understand that cos(θ) represents the cosine of an angle θ.
Step 2: Know that cos(45°) is a common value in trigonometry.
Step 3: Recall that cos(45°) = √2/2.
Step 4: Calculate √2/2, which is approximately 0.707.
Step 5: Since cos(θ) = 0.707, we can conclude that θ = 45°.
