Determine whether the two angle measurements can be supplementary if m LA = 37°
and m LB = 143°. What is the reasoning behind the answer?
(1 point)
• No, they do not add up to 180°
• No, they do not add up to 90°
• Yes, they are a supplementary pair.
• No, they are not adjacent.

No, they do not add up to 180°. This is because the sum of two angles must be 180° in order for them to be supplementary.
