Answer 1

I think so 1,3and4 are complementary

Answer 2

Hey friend,

Here is your answer,

_____________________________________________________________

Complementary angles are those angles whose sum is 90°.

Here the options are:-

1.) 70° and 20°

70° + 20°

= 90°

{Hence this pair is of complementary angles}

2.) 75° and 25°

75° + 25°

= 100°

{Hence this pair is not of complementary angles}

3.) 48° and 52°

48° + 52°

= 100°

{Hence this pair is not of complementary angles}

4.) 35° and 55°

35° + 55°

= 90°

{Hence this pair is of complementary angles}
