The circle is divided into two sectors. The angle of the two vectors is 50 and 210. The angle of the third sector is calculated.

Since there are 360 degrees in the circle, and the angles of the two sectors are 50 and 120 degrees, respectively, to get the angle of the third sector, you need to subtract the sum of the known angles of the sectors from 360, the angle of the third sector will be: 360- (120 + 50) = 360-170 = 190.

Answer: 190 degrees.
