Answer:
41° and 139°
45° and 145°
Step-by-step explanation:
Supplementary angles refers to two angles which measures up to 180°.
Therefore, it is safe to say that, angle in supplementary angles = 180°
23° and 147°
= 23° + 147°
= 170°
Not supplementary
41° and 139°
= 41° + 139°
= 180°
Supplementary angle
30° and 60°
= 30° + 60°
= 90°
Not supplementary angle
45° and 145°
= 45° + 145°
= 180°
Supplementary angle
