Answer:
NOT SURE, but since no one is answering, then x= 40
Step-by-step explanation:
(4x - 50) = (2x+30)
4x - 50 = 2x + 30
4x - 2x = 30+50
2x = 80
x = 80/2
x = 40
Two angles are alternate and has same measurement because line l and line m are parallel so to find x:
4x - 2x = 30 + 50 add/subtract like terms
2x = 80 divide both sides by 2
