Final answer:
Angle x measures 41°, as supplementary angles add up to 180°, and Angle y is given as 139°.
Step-by-step explanation:
If Angle x and Angle y are supplementary angles, this means that their measures add up to 180 degrees. Given that Angle y measures 139°, we can find the measure of Angle x by subtracting the measure of Angle y from 180°:
- Identify the total measure of supplementary angles: 180°.
- Subtract the given angle (Angle y = 139°) from 180° to find Angle x.
- Calculation: 180° - 139° = 41°.
If angle y measures 139 degrees, we can find the measure of angle x by subtracting angle y from 180:
Angle x = 180 - angle y = 180 - 139 = 41 degrees
Therefore, the measure of Angle x is 41°.
