Supplementary angles always add up to 180. So you need to subtract 30 from 180. Which would give you 150. So 150 is your answer!

x=18, m∠1=140, m∠2=40

Step-by-step explanation:

m∠1 and m∠2 will equal up to 180

7x+14+2x+4=180

Combine like-terms

9x+18=180

Subtract 18 from both sides.

9x=162

Divide both sides by 9

x=18

Then plug in 18 for x in the angle measures

7(18)+14=140

2(18)+4=40
