If sin(θ) = 0.866, what is θ in degrees? (2020)
Steps
Concepts
Step 1: Understand that we need to find the angle θ where the sine value is 0.866.
Step 2: Recall the sine values of common angles. One of the known values is sin(60°).
Step 3: Calculate sin(60°). It is equal to √3/2.
Step 4: Approximate √3/2. It is approximately equal to 0.866.
Step 5: Since sin(60°) = 0.866, we can conclude that θ = 60°.
Trigonometric Functions
– Understanding the sine function and its values for common angles.
Inverse Trigonometric Functions
– Using inverse sine to find angles from sine values.
