To determine the measure of an exterior angle \( x \), we need more context, such as information about an interior angle or the geometry involved.
In a polygon, the measure of an exterior angle can be calculated using the formula: \[ x = 180^\circ - \text{(interior angle)} \]
In a triangle, the sum of the measures of the exterior angles is always \( 360^\circ \). If you provide additional information or context about the angles involved or the shape in question, I can help you find the value of \( x \).
