Q. Determine the number of different values that x \angle x could be based on the given information.\newlinesinx=0.4048 \sin x=0.4048 \newline33\newline00\newline11\newline22
  1. Identify sine value: First, we know that sinx=0.4048\sin x = 0.4048. The sine function is positive in the first and second quadrants.
  2. Calculate reference angle: To find the reference angle, we use the inverse sine function on a calculator: x=sin1(0.4048)x = \sin^{-1}(0.4048).
  3. Determine angle in first quadrant: Calculating the reference angle gives us x23.9x \approx 23.9 degrees. This is the angle in the first quadrant.
  4. Find angle in second quadrant: The second possible angle is in the second quadrant, which is 18023.9180 - 23.9 degrees =156.1= 156.1 degrees.
  5. Final possible values: So, there are two possible values for x\angle x: 23.923.9 degrees and 156.1156.1 degrees.
