Lines l, m, and n are parallel. What is the value of x? ° Parallel lines labeled, top to bottom, l, m, and n. A transversal forms a seventy-three degree angle that lies to right of the transversal and above line l and an angle with x degrees that is to right of transversal and below line n.

180 = x + 73
Well. If you look, the angles around line l are 73 and we don't know what the other one is. We know that since it is a straight line the angles will have to equal 180. So 180-73 = 107. So 73 and 107 are the degrees for every angle on those 4 lines. So x = 107.
