If L (3x + 50 degrees)is parallel to M (2x - 20 degrees) find X.

  • math - ,

    What is L and M? Lines? IF so, what is this degree business in the parenthesis?

    If L and M are angles, how can angles be parallel.

    I can make no sense of what you posted.

  • math - ,

    I assume you mean
    the slope of Line L = 3x+50
    the slope of line M = 2x-20

    If the lines are parallel, the slopes are equal. So,

    3x+50 = 2x-20
    x = -70
