... Triangle ABC is inscribed in a circle, centre O. ∠AOB = 100º and ∠COB = 140º Determine the values of xº, yº, and zº. What’s the angle of a full circle? 360º. So, the angle all the way around the origin needs to add up to 360º. 100º + 140º + xº = 360º xº = 120º yº is an inscribed angle. What’s ...
