Option 3


Hope it helps

Answer 2

Solution :

Option ( 3 ) is correct.

Explanation :

*******************************************
Two angles are said to be

complementary if their sum is 90°

*******************************************

Here,

one angle ( x ) = 55°

Let the second angle = y

x + y = 90°

=> y = 90° - x

=> y = 90° - 55°

=> y = 35°

Therefore ,

Complementary angle of 55° is 35°
