To determine the value of \( x \) in a triangle, more information is typically needed, such as the lengths of the sides or the measures of the angles. The choices given (42, 42, 84, 84) suggest that \( x \) might be an angle or part of a calculation related to the triangle's properties.

Given that the sum of the angles in any triangle is \( 180^\circ \), it is possible that \( x \) is related to the angles.

If two of the angles are each \( 42^\circ \), the third angle, \( x \), would be:
\[
x = 180^\circ - 42^\circ - 42^\circ = 96^\circ
\]
However, since none of the options is \( 96^\circ \), it's more likely that \( x \) could be an angle of \( 42^\circ \) or \( 84^\circ \).

To provide an accurate solution, the context or a diagram of the triangle would be necessary.
