Question

12. Find out the supplements of the following angles :
(i) 90°
(ii) 10°
(iii) 81°
13. Find out the complements of the following angles :
(i) 81°
(ii) 10°
(iii) 27°
111​

Answer 1

Supplements:

A supplement is the other angle which when added to given angle equals 180.

(i) 90 + x = 180

x = 180 - 90

x = supplement = 90

(ii) 10 + x = 180

x = 180-10

x = supplement = 170

(iii) 81 + x = 180

x= 180-81

x = supplement = 99

Complements:

A complement is the other angle which when added to given angle equals 90.

(i) 81 + x = 90

x= 90-81

x = complement = 9

(ii) 10 + x = 90

x= 90-10

x = complement = 80

(iii) 27 + x = 90

x=90-27

x = complement = 63

Answer 2

Answer:

Hey mate! here is your answer

The supplementary angle = 180°

(i) 180 - 90 = 90°

(ii) 180 - 10 = 170°

(iii) 180 - 81 = 99°.

The complementary angle = 90°

(i) 90 - 81 = 9°

(ii) 90 - 10 = 80°

(iii) 90 - 27 = 63°.
