Use the relationship between supplementary angles to determine the value of y° if x°=125°.

Answer 1

Supplementary angles are two angles that add up to 180 degrees.

If x° is one of the angles and it equals 125°, then the other angle, y°, can be determined by subtracting x° from 180°.

y° = 180° - x°

Substituting x° = 125° into the equation:

y° = 180° - 125°
y° = 55°

So, if x° = 125°, then y° = 55°.
