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
