Sam is attempting to explain how to find the value of the missing angle in the problem above. His explanation should be that the angles are ______________________.

• complimentary, so he should subtract 61 from 90.

• complimentary, so he should subtract 61 from 180.

• supplementary, so he should subtract 61 from 90.

• supplementary, so he should subtract 61 from 180.
