Questions & Step-by-Step Solutions

If sin(x) = 1/2, what is the value of x in degrees?
Correct Answer: 30°
  • Step 1: Understand that we need to find the angle x where the sine value is 1/2.
  • Step 2: Recall the sine values of common angles. One of them is sin(30°).
  • Step 3: Check if sin(30°) equals 1/2. Yes, it does.
  • Step 4: Conclude that x = 30° because sin(30°) = 1/2.
  • Trigonometric Functions – Understanding the sine function and its values at specific angles.
  • Inverse Trigonometric Functions – Recognizing that sine can have multiple angles that yield the same value.
