Question

in the given figure O is the centre angle BOC 130 degree angle AOB 110 degree what is the measure of angle AOC find the angles of triangle ABC

Answer 1

120 degree angle AOC

Answer 2

Answer(1):Ao=Bo. So ∆ABC=180°

Ao=55°so bo=55°. So ∆ ABC=110 given so 180-110=70

Step-by-step explanation: (2)another method we know some of opposite cycle quadrilateral∆ is 180 so centre O is 110 = 70
