Question

Complementary angle of 20degree is 70degree​

Answer 1

Answer:

37  degree

Step-by-step explanation:

Two angles are called complementary angles, if their sum is one right angle i.e. 90°.

Each angle is called the complement of the other.  

Example, 20° and 70° are complementary angles, because 20° + 70° = 90°.

Clearly, 20° is the complement of 70° and 70° is the complement of 20°.

Thus, the complement of angle 53° = 90° - 53° = 37°.

Here is your answer. Mark me as brainly

Answer 2

Answer:

yes it is correct

Step-by-step explanation:

Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees. One way to avoid mixing up these definitions is to note that s comes after c in the alphabet, and 180 is greater than 90.

20°+70°=90°(Complementary angle)
