Wierd Geometry

  1. Sep 9, 2004 #1
    I was doing my geometry homework earlier and came across a problem:

    Find m<S if m<S is 20 more than four times its supplement.

    What I did:
    m<S= x
    supplement of m<S: x = (x-180)

    how I worked it out:
    x=4(x-180) + 20
    233.333... = x

    My answer for x is obviously wrong because when I try to find m<S, I get 233.33... again:
    x=4(2.333...-180) +20
    4(53.33...)= 213.333... + 20 = 233.3333....

    This evidently does not make any sense at all. The problem said "supplement", and 233.333... is most certainly not an angle measure which agree with the definition of supplement, I believe.

    Please help.

    okay. That does not make a difference.
