Use the relationship between supplementary angles to determine the value of y° if x°=125° .(1 point)Responses55°55 degrees35°35 degrees125°125 degrees305°
The relationship between supplementary angles is that they add up to 180 degrees.
In this case, x° and y° are supplementary angles, so we can set up the following equation:
x° + y° = 180°
Substituting x° = 125°:
125° + y° = 180°
Now, we can solve for y° by subtracting 125° from both sides of the equation:
y° = 180° - 125°
y° = 55°
Therefore, the value of y° is 55 degrees.
