The circle was divided into three sectors. The angles of the two sectors are equal: 1) 40 degrees

The circle was divided into three sectors. The angles of the two sectors are equal: 1) 40 degrees and 90 degrees, 2) 150 degrees and 70 degrees, 3) 50 degrees and 210 degrees. Calculate the angle of the third sector

the circle is only 360 degrees, so we can calculate the third angle as follows: we find out how many degrees are in two known sectors, and then subtract the resulting sum from 360 degrees.
1). 360- (40 + 90) = 230 degrees;
2). 360- (150 + 70) = 140 degrees;
3). 360- (50 + 210) = 90 degrees.
