Angel M and Angel N are supplementary angles. If Angel M is nine more than one half Angel N, what are the measures of the angels?

    Angels can't be measured.

  • pre-algebra -

    m+n = 180
    m = 9 + .5n
    so
    9 + .5 n + n = 180
    1.5 n = 171
    n = 114
    m = 180-114

  • pre-algebra -

    I forgot to mention that.
