Q
Q: If sin(θ) = 1/2, what is the possible value of θ? (2022)
Solution:
sin(30°) = 1/2, so θ = 30°.
Steps: 5
Show Steps
Step 1: Understand that sin(θ) = 1/2 means we are looking for an angle θ where the sine value is 1/2.
Step 2: Recall that the sine of an angle in a right triangle is the ratio of the opposite side to the hypotenuse.
Step 3: Remember that sin(30°) is a well-known value, which equals 1/2.
Step 4: Therefore, one possible value of θ is 30°.
Step 5: Note that sine is positive in the first and second quadrants, so another possible value is θ = 180° - 30° = 150°.
