Answer 2

Solutions :-

What is Complementary angles ?
=> When the sum of two angles is 90°, then the two angles are said to be complementary angles.

Example :- If x + y = 90°, x and y are the complementary angles.



Q: Find the complementary angle of 2/5 right angle.

=>
Find the 2/5 of right angle :-

= 2/5 of 90°
= 0.4 × 90°
= 36°


Now,
Find the complementary angle of 36° :-

= 90° - 36°
= 54°


Hence,
54° is the complementary angle of 2/5 right angle.
