Question

An angle is 20 degree less than it's complement. find the measure of the angle​

Answer 1

Let the angle be X degree. Given that, Angle - Supplement = 30. Hence, the angles are 105 and 75 degrees.

Answer 2

Answer:

Complementry angles are those angles whose sum is 90.

Let the angle be x so it’s complementry angle will be 90-x.

Now x is 20 less than it’s complementary angle so,

x=(90-x)-20

x=70-x

2x=70

x=35
