Answer 1

In the circle we know that the measure of the angle is formed on the center is twice of the angle is formed other side of the circle

GIVEN THAT:-

< AOB = 80°

so the measure of angle OCB = 40°

• since AOC is a straight line

so the measure of angle BOC = 100°

• we know that the sum of all angles in a triangle is equal to 180°

so the measure of angle OBC = 40°

CONCLUSION:-

OCB = OBC = 40°
