Answer 1

Answer:

65° + 115° = 180°

They are supplementary angles.

Answer 2

Answer:

i): 65° + 115° = 180°

They are supplementary angles.

ii): 63° + 27° = 90°

They are complementary angles.

iii): 112° + 68° = 180°

They are supplementary angles.

iv): 130° + 50° = 180°

They are supplementry angles.

v): 45° + 45° = 90°

They are complementary angles.

vi): 80° + 10° = 90°

They are complementary angles.
