Question

pls tell me the correct ans i dont want any improper answer

Answer 1

Answer:

The answer is (70+a) °

Step-by-step explanation:

a+20°=90°

(complementary angle is of 90°)

a°+20°=90°

a°=90°-20°

a°= 70°

so the complementary angle is 70°

Hope it will help you and please follow me!!

Answer 2

Answer:

Complementary angle of (a + 20)° is = (70 - a)°.

Step-by-step explanation:

The sum of any any angle and it's complementary angle is 90°.

Therefore, the complementary angle of an angle is the angle itself subtracted from 90°.

Therefore, complementary angle of (a + 20)° is [90 - (a + 20)]° = (70 - a)°

Therefore, the second option is the correct answer.
