Q
Q: If cos(θ) = 1/2, what is θ in degrees?
Solution:
cos(60°) = 1/2, so θ = 60°
Steps: 5
Show Steps
Step 1: Understand that cos(θ) means the cosine of angle θ.
Step 2: Recall that the cosine function gives the ratio of the adjacent side to the hypotenuse in a right triangle.
Step 3: Know that cos(60°) equals 1/2 from trigonometric values.
Step 4: Since cos(θ) = 1/2, we can set θ equal to 60°.
Step 5: Conclude that θ = 60°.
