Determine whether the two angle measurements can be supplementary if m∠A = 37° and m∠B = 143°. What is the reasoning behind the answer?
(1 point)
No, they are not adjacent.
Yes, they are a supplementary pair.
No, they do not add up to 90°.
No, they do not add up to 180.
No, they are not a supplementary pair. Supplementary angles are two angles that add up to 180°. However, in this case, m∠A + m∠B = 37° + 143° = 180°, so they are a supplementary pair. The reasoning behind the answer is that the sum of these two angles is equal to 180°, which meets the definition of supplementary angles.

a .No, they are not adjacent.
b .Yes, they are a supplementary pair.
c .No, they do not add up to 90°.
d .No, they do not add up to 180.
d. No, they do not add up to 180°. The reasoning behind the answer is that for two angles to be supplementary, their sum must be 180°. However, in this case, m∠A + m∠B = 37° + 143° = 180°, so they are a supplementary pair.
Are the angles supplementary if m∠A = 98° and m∠B = 88°? D
(1 point)
a.No, they do not add up to 180.
b. No, they are not adjacent.
c.No, they do not add up to 90.
d. Yes, they are a supplementary pair.
a. No, they do not add up to 180°. The reasoning behind the answer is that for two angles to be supplementary, their sum must be 180°. In this case, m∠A + m∠B = 98° + 88° = 186°, which is greater than 180°. Therefore, the angles are not supplementary.
Use the relationship between supplementary angles Za and Zb. What is m∠a if mb121°? (1 point)
a. 59°
b. 121
c. 31
d.301
If m∠b = 121° and angles a and b are supplementary, then we can determine m∠a by subtracting m∠b from 180° (since supplementary angles add up to 180°).
m∠a = 180° - m∠b = 180° - 121° = 59°.
Therefore, the answer is a. 59°.
Angles a and b are supplementary angles. What is the value of m∠a if m/b43°? (1 point)
43
47°
223
137
If m∠b = 43° and angles a and b are supplementary, then we can determine m∠a by subtracting m∠b from 180° (since supplementary angles add up to 180°).
m∠a = 180° - m∠b = 180° - 43° = 137°.
Therefore, the value of m∠a is 137°.
