see the attachment guys, i have no idea on how to solve this problem


QUESTION: what is the 100 and 140 degrees on the corners refering to? it is part of the cirumference????

360 degrees makes up a circle... so those angles added up gives us 240, so that means the arc is 120 degrees. angle x is going to be half of that by using some equation that i forgot. but yeah, i'm pretty sure those numbers are the circumference converted from radians to degrees

the answer is 30
