Answer 1

Answer:

I don't know sorry please please that's ok

Answer 2

The angle is 69° which is 42 degree less than its supplement.

Step-by-step explanation:

• Given that

        Let angle = X

        Its supplement = 180° - X

• Here it is given that measure of an angle is 42 degree less than its supplement.

       This can be written in mathematical term, like as

• X = 180° - X - 42°

• On simplification

        2X = 138°

• On dividing by 2 on both side, we get

• X = 69° = This is the angle which is 42 degree less than its supplement.
