Answer:12

Step-by-step explanation:

6x+48+60=180

since supplementary angles equal 180 degrees you would set up the equation like above

Then you would add 48 and 60 which will give you 108.

6x+108=180

Then subtract 108 from both sides adn you get

6x=72

divide both sides by 6 and your final answer is

x=12
