A,B,C,D,E are 5 points placed randomly on the circumference of a circle. Every point is joined with the points that are not adjacent to it by straight line segments. What is the sum of the angles at the vertices of the star so formed?
ans is 180
approach plz
@brpedu refer to figure below.
angle DOC + BOC + AOB + EOA + EOD = 360.
Angle at the circumference is 1/2 the angle at the center.
so 360/2 = 180..

On the morning of friendship day, a teacher took n friendship bands to her class intending to distribute these bands among her students. she calculated that these would be exactly sufficient, if every student of her class gave one band to every other student in the class. However exactly 2 students had not turned up and hence exactly n-50 were used up. if in the afternoon exactly 1 of these two students turned up, find the number of bands that remained unused.
