Answer 2

Step-by-step explanation:

(1)40°

Complementary angle of 40° is 90-40=50°

(2)639°

Complementary angle of 639° is 90-639= -549°

(3)45°

Complementary angle of 45° is 90-45=45°

(4)55°

Complementary angle of 55° is 90-55=35°

(5)20°

Complementary angle of 20° is 90-20=70°

(6)90°

Complementary angle of 90° is 90-90=0°

(7)x°

Complementary angle of x° is 90-x=(90-x)°

(8)(90-x)°

Complementary angle of (90-x)° is 90-x-90=(-x)°

(9)5°

Complementary angle of 5° is 90-5=85°

(10)(180-x)°

Complementary angle of (180-x)° is 180-x-90=(90-x)°
