Answer:
41°
Step-by-step explanation:
Supplementary angles are angles that has their sum total of angles as 180°.
If two angles ∠x and ∠ y are supplementary, this means
∠x+∠y = 180° ... (1)
Since ∠y = 139°, to get ∠x, we will substitute the value of ∠y in equation 1 to have;
∠x + 139° = 180°
∠x = 180°-139°
∠x = 41°
Therefore the measure of ∠x is 41°
