In the fig. ‘O’ is the centre of Circle. Chords AC and BD intersect at right angles at E, if 
= 35° then 
Here we used the concept of angle sum property of a triangle. When two lines cross at one point, a linear pair of angles is created. If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°. So here the angle EBC is 35 degree.
