finals next weekk D:

ten less than three times the complement of an angle is it supplement.

find the measure of the supplement?

  • math geo please help? -

    Write that as an equation. Let x be "the angle", so 180 -x will be the supplement.

    The complement of x is 90-x

    Your statement can be written:

    3*(90 - x) -10 = 180 - x

    Now solve that.
    260 -3x = 180 - x
    2x = 80
    x = 40
    So, what is the supplement of x?

  • math geo please help? -

    supplement of x is 140?
