Question

Find the values of x and y that make k || j and m || n.

Answer 1

Same side interior angles CONVERSE also called consecutive interior angle CONVERSE.
IF  (x - 30) + (x + 50) = 180 then, line line n || m.

x -  30 + x + 50 = 180
2x + 20 = 180
subtract 20 from both sides
2x = 160
divide both sides by 2
x = 80

IF (x - 30) + y = 180, then k || j.
(80 - 30) + y = 180
50 + y = 180
subtract 50 from both sides
y = 130

Answer 2

Answer:

80

130
