Explanation:
When the sum of two angles is equal to 90o, they are called complementary angles. In this case, both angles are called complementary to each others. For example 30o and 60o, 40o and 50o, 20o and 70o, etc. are complementary angle since their sum is equal to 90o.
complementary angles
Sum of angles in fig (i) = 70° + 20° = 90°
Hence, they are complementary.
Sum of angles in fig (ii) = 75° + 25° = 100°> 90°
Hence, they are not complementary.

Answer: Let us assume the required complementary angle is x
So,

Hence, the required complementary angle = 45°
Answer: Complementary angles are two angles that add up to exactly
90 degree
Example:- 40 and 50
=40+50
= 90
Explanation:
a) 45°
=Let the complement angle be x
45+x = 90
x= 90-45
x=45
b) 32°
32+x = 90
x=90-32
x=58
c) 46°
46+x=90
x= 90-46
x=44
d)28°
28+x = 90
x= 90-28
x=62
