To solve for \( x \) and determine which of the options is correct, we need more information about the equation or context in which \( x \) is being solved.
However, based on the responses provided, it seems like you may be working with angles. The options suggest that \( x \) could be an angle in degrees.
If you have a specific equation, triangle, or any additional context that relates to \( x \), please provide it, and I can help you solve for \( x \). Otherwise, I cannot determine the correct answer solely based on these multiple-choice options.
