Answer 4

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

Answer 5

No, they do not add up to 180°.
The definition of supplementary angles is that they add up to 180°. In this case, 37° + 143° = 180°, so the two angles are indeed supplementary.

Answer 6

No, they do not add up to 180°.
The definition of supplementary angles is that they add up to 180°. In this case, 98° + 88° = 186°, so the two angles are not supplementary.

Answer 7

Since supplementary angles add up to 180°, if m∠b = 121°, then m∠a = 180° - 121° = 59°.

Answer 8

Since supplementary angles add up to 180°, if m∠b = 43°, then m∠a = 180° - 43° = 137°.
Therefore, the value of m∠a is 137°.

Answer 9

Since supplementary angles add up to 180°, if x° = 125°, then the other angle (y°) is given by:

y° = 180° - x°
y° = 180° - 125°
y° = 55°

Therefore, the value of y° is 55°.
