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?

• pre-algebra -

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.
