Question

In the given figure, prove that m || n.
angle a =63, angle c = 38, angle b = 25​

Answer 1

Answer:

Two angles whose sum is 90° are called complementary angles.

(i) Complement of 55° = 90° − 55° = 35°

(ii) Complement of 16°=(90−16)°16°=90-16°=74°=74°

(iii) Complement of 90° = 90° − 90° = 0°

(iv) 23 of a right angle⇒(90×23)°=60°23 of a right angle⇒90×23°=60°

Complement of 23 of a right angle=(90−60)°=30°
