use the relationship between suppmentary angles to determine the value of y is x = 125
If x = 125, then the two angles are supplementary, which means they add up to 180 degrees.
Since x = 125 and y is the other angle, we have:
125 + y = 180
Subtracting 125 from both sides, we get:
y = 180 - 125
y = 55
Therefore, if x = 125, y = 55.
