Question

If line L is parallel to line M, what is the value of x?
Please provide an explanation if you can! Thanks

Answer 1

A line is 180° so if you are given 43°on part of line l

180-43=137

So x=137°

Answer 2

The answer is simple since the lines are parallel the 43 degrees carry over to the other line and since it is a straight line the whole thing adds up to 180 degrees the degree is 137
