Question

pls pls tell me the correct answer

Answer 1

Answer:

Complementary angle of (20 + r + s)° is (70 - r - s)°

Step-by-step explanation:

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

Therefore, complementary angle is the angle subtracted from 90°

Therefore, complementary angle of (20 + r + s)° is [90° - (20 + r + s)°]

= (90° - 20° - r° - s°) = (70 - r - s)°

Therefore, the first option is the correct answer.
