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.
