    82 degrees

    Step-by-step explanation:

    So a supplemental angle has the equation A = (180-B)

    Start with writing a formula. A is the angle you need to find.

    A+B=180

    A=B-16

    Use substitution.

    B-16+B=180

    2B=196

    B=98

    Use substitution again.

    A+B=180

    A+98=180

    A=180-98

    A=82
