    |dw:1440603132208:dw| that straight line add up to 1180 degree right so if what would you add into 55+65 to get 180 ?

    Yeah, arc NB is 55 degrees (angle NEB is vertical angle of angle MEA =55 degrees) @OM14forever BUT question asks arc MEB, so the arc must pass through E, so it's the major arc that you need. What do you think it is?
