PLEASEEEE SOMEONEEEE

Step-by-step explanation:
If m and n are parallel, then these two interior angles are supplementary...they sum to 180 degrees
3x-30 + 2x = 180
5x = 210
x=42
Answer:
42
Step-by-step explanation:
[tex](3x-30)^{0} +2x^{0} =180^{0}[/tex]
[tex]5x-30=180[/tex]
[tex]5x=180+30[/tex]
[tex]x=210/5=42[/tex]
Hope this helps.
