Question

write the complementary and supplementary of angles of (a)75° (b) 60°​

Answer 1

Answer:

complemantery angle of 75°=15° and 60°=30°.

supplementary angles of 75°=105°and 60°=120°

Answer 2

$\huge\sf\red{Concept}$

Sum of complementary angles = 90°

Sum of Supplementary angles = 180°

_______________________________

So,If they given any angle to find complementary and suplementary of an angle How to find Lets see!!here

a) Complement of 75° =

As we know that Sum of complementary angles is 90°

So, Let the angle be x

Therefore 75° + x =90°

x = 90°-75°

x = 15°

So, complement of 75° is 15°

b) Complement of 60°

Therefore

60+ x = 90°

x = 30°

a) Supplementary angle of 75° is

As we know that Supplemntary angles should be 180°

So, 75+x = 180°

x = 105°

b) Supplementary angle of 60°

60 + x = 180

x = 120

____________

So finall answers

Complementary angle of 75° is 15°

Supplementary angle of 75° is 105°

Complementary angle of 60° is 30°

Supplementary angle of 60° is 120°
