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

Answer 1

If the angles x° and y° are supplementary, it means that they add up to 180°. Given that x° = 125°, we can use the relationship between supplementary angles to find the value of y°.

x° + y° = 180°
125° + y° = 180°

To solve for y°, we subtract 125° from both sides:

y° = 180° - 125°

Simplifying, we have:

y° = 55°

Therefore, if x° = 125°, then y° = 55°.
