It seems like your question got cut off, and I need more information to help you find the measure of the exterior angle \( x \). Typically, in a polygon or triangle, the exterior angle can be calculated based on the corresponding interior angle or using the property that the sum of the measures of the exterior angles of any polygon is \( 360^\circ \).
If you have specific values or a context around a polygon or shape, please provide that information for a more accurate answer.
