What is the value of x? 100 , 120 , 130 , 150?

The first thing that would would want to first do, we would then want to add up at the numbers in this figure, and the work would be done below.

[tex]\boxed{140+34++56=230} \ ... \ \boxed{230-360-130}[/tex]

Then,we would then have the result of the numbers added, and then, subtract it from 360°, knowing that this would be the sum of everything.

[tex]\boxed{\bf{x=130}}[/tex]
