Answer 2

well we know the line will be equal to 180 degrees so we will have an equation like this

x+100+3x=120

we subtract 100 from 180 to get 80.

180-100=80

however x cannot be 80 bc we still have the 3x.

when you do the math, you will see that 20 times 3 is 60.

20×3=60

going even further we see that 60 plus 20 is 80

60+20=80

so to check our work, lets solve this equation

20+100+3×20=180

20+100=120

3×20=60

120+60=180

so your answer is x=20
