angle bce+ angle bcd=180
35+angle bcd =180
angle bcd = 180-35
= 145
angle bcd +angle bad=180 (sum of opp. angles of a cyclic quad. is 180)
145 + angle bad =180
angle bad= 35
angle bod = 2× angle bad. (the angle subtended by an arc on centre is double the angle subtended by it at any point on the remaining circle)
angle bod= 2×35
= 70
