Question

Complementary angle of 30 degree , 80 degree , 11 degree , 87 degree
​

Answer 1

Answer:

60, 10,79,3

Step-by-step explanation:

Two angles are said to be complementary angles when their sum will be 90 degree

so

complementary angle of 30 is 60 degree

complementary angle of 80 is 10 degree

complementary angle of 11 is 79 degree

complementary angle of 87 is 3 degree

Answer 2

Answer:

complementary angle=90°

so compementary angle of 30 degree is

x+30°=90°

x=90°-30°=60°

complementary angle of 80degree is

x+80°=90°

x=90°-80°=10°

complementary angle of 11° is

x+11°=90°

x=90°-11°=79°

complementary angle of 87° is

x+87°=90°

x=90°-87°=3°
