Use the relationship between supplementary angles to determine the value of y° if x°=125° . (1 point) Responses 35° 35 degrees 55° 55 degrees 125° 125 degrees 305° 305 degrees
Since supplementary angles add up to 180 degrees, if one angle is x°, then the other angle is 180° - x°.
So, if x° is equal to 125°, then y° would be equal to 180° - 125° = 55°.
Therefore, the value of y° is 55 degrees.
