Given angles of 80° and 100°, determine if they are complementary or supplementary

Are they complementary or supplementary?
Two angles are complementary if their sum is equal to 90° and are supplementary if their sum is equal to 180°
Angle 1 + Angle 2 = 80° + 100°
Angle 1 + Angle 2 = 180°
Since the sum of the two angles ≠ 90°, the two angles are not complementary
Since the sum of the two angles equals 180°, the two angles are supplementary
