Help bro im stuck as a bug in a rug pls help i know it corny pls just help

i say the answer is 120.

i added the other numbers first 110 + 130=240

A circle is usually 360 degrees i say, so i subtracted 360-240=120 degrees

the answer is m<QTR= 120 degrees

if you add all the numbers together it makes 360 so i say its a valid answer
