Answer:
40 degrees
Step-by-step explanation:
Supplementary angles are angles in which their measures combined add up to 180 degrees. So we can set up an equation:
140+x=180
x=40
So the other supplementary angle is 40 degrees
Answer:
x = 61
Step-by-step explanation:
The angle above the line n adjacent to 2x - 6 is (x + 3) alternate angle.
Adjacent angles are supplementary, thus
2x - 6 + x + 3 = 180, that is
3x - 3 = 180 ( add 3 to both sides )
3x = 183 ( divide both sides by 3 )
x = 61
