Answer 1

$\huge\purple{Required \: Answer :}$

Complementary pair of angles are the pairs which measures Sum of 90°

(1)

=> Yes, It is the pair of complementary angles.

(2)

=> No, It is not the pair of complementary angles.

(3)

=> Yes, It is the pair of complementary angles.

Answer 2

Answer:

1 and 3 are complementary angles.

Complementary angles are those 2 angles whose sum are 90 degrees.So,in 1st one it is 70° and 20° and their sum is 90°.So these 2 are complementary angles.In 2nd It is 75° and 25° and their sum is 100°.So these 2 can't be complementary angles.In 3rd case,It is 35° and 55° and it's sum is 90°.So these 2 can be complementary angles.Hence 1st and 3rd are complementary angles while 2nd is not.
